[U-Boot-Users] [PATCH 00/20] [new uImage] patchset 7 - core functionality

[Bartlomiej Sieka]

Hello,

This patch series implements the core of the new uImage support functionality,
i.e., the actual booting of images in new format, as well as support in
auxiliary commands that operate on images. There are also few fixing patches
in the series.

The patchset concludes major development work on the new uImage format, with
one missing piece (MD5 support) to be posted in a day or two.  Generally, the
new format supports everything that the old format does, with the exception of
XIP and standalone applications. Also, only booting of the Linux kernel is
supported. If there are people interested in contributing to these areas,
please step forward.

It's a good moment to thank everybody who helped with this effort by
commenting on requirements, etc., and those who helped by reviewing patches.
At the same time it's important that people help with testing. The patchset 7
code is already available in the new-image branch of the u-boot-testing
repository -- please pull the code and try it out on the boards that you care
about. Reading doc/uImage.FIT/howto.txt should be sufficient to get you
started. Note that adding support for the new image format increases the size
of U-Boot, so depending on your Flash sector layout, adjustments to
CFG_MONITOR_LEN might be necessary.

The code builds on all architectures, and has been tested on ppc, but more
thorough testing is needed. In particular, reports on test results of the
following areas not tested due to hardware unavailability will be greatly
appreciated:
- boards other that ppc
- booting from dataflash
- U-Boot commands:
  - diskboot
  - docboot
  - fdcboot
  - fpga
  - nboot
  - scsiboot
  - usbboot

Regards,
Bartlomiej

[U-Boot-Users] [PATCH 02/20] [new uImage] Add support for new uImage format to mkimage tool

[Bartlomiej Sieka]

Support for the new uImage format (FIT) is added to mkimage tool.
Commandline syntax is appropriately extended:

mkimage [-D dtc_options] -f fit-image.its fit-image

mkimage (together with dtc) takes fit-image.its and referenced therein
binaries (like vmlinux.bin.gz) as inputs, and produces fit-image file -- the
final image that can be transferred to the target (e.g., via tftp) and then
booted using the bootm command in U-Boot.

[U-Boot-Users] [PATCH 06/20] [new uImage] Remove unnecessary arguments passed to ramdisk routines

[Bartlomiej Sieka]

[U-Boot-Users] [PATCH 08/20] [new uImage] ppc: Add new uImage format support to FDT handling routines

[Bartlomiej Sieka]

From: Marian Balakowicz <m8@semihalf.com>

Support for new (FIT) format uImages is added to powerpc specific
boot_get_fdt() routine which now recognizes, sanity checks FIT image
and is able to access data sections of the requested component image.

[U-Boot-Users] [PATCH 09/20] [new uImage] Add node offsets for FIT images listed in struct bootm_headers

[Bartlomiej Sieka]

From: Marian Balakowicz <m8@semihalf.com>

This patch adds new node offset fields to struct bootm_headers
and updates bootm_headers processing code to make use of them.
Saved node offsets allow to avoid repeating fit_image_get_node() calls.

[U-Boot-Users] [PATCH 11/20] [new uImage] Add new uImage format support to autoscript routine

[Bartlomiej Sieka]

From: Marian Balakowicz <m8@semihalf.com>

autoscript() routine is updated to accept second argument, which
is only used for FIT images and provides a FIT subimage unit name.

autoscript() routine callers must now pass two arguments. For
non-interactive use (like in cmd_load.c, cmd_net.c), new environment
variable 'autoscript_uname' is introduced and used as a FIT
subimage unit name source.

autoscript command accepts extended syntax of the addr argument:
addr:<subimg_uname>

+Command syntax extensions for the new uImage format
+===================================================
+
+Author: Bartlomiej Sieka <tur@semihalf.com>
+
+With the introduction of the new uImage format, bootm command (and other
+commands as well) have to understand new syntax of the arguments. This is
+necessary in order to specify objects contained in the new uImage, on which
+bootm has to operate. This note attempts to first summarize bootm usage
+scenarios, and then introduces new argument syntax.
+
+
+bootm usage scenarios
+---------------------
+
+Below is a summary of bootm usage scenarios, focused on booting a PowerPC
+Linux kernel. The purpose of the following list is to document a complete list
+of supported bootm usages.
+
+Note: U-Boot supports two methods of booting a PowerPC Linux kernel: old way,
+i.e., without passing the Flattened Device Tree (FDT), and new way, where the
+kernel is passed a pointer to the FDT. The boot method is indicated for each
+scenario.
+
+
+1.  bootm               boot image at the current address, equivalent to 2,3,8
+
+Old uImage:

+New uImage argument syntax
+--------------------------
+
+New uImage support introduces two new forms for bootm arguments, with the
+following syntax:
+
+- new uImage sub-image specification
+<addr>:<sub-image unit_name>
+
+- new uImage configuration specification
+<addr>#<configuration unit_name>
+
+
+Examples:
+
+- boot kernel "kernel at 1" stored in a new uImage located at 200000:
+bootm 200000:kernel at 1
+
+- boot configuration "cfg at 1" from a new uImage located at 200000:
+bootm 200000#cfg at 1
+
+- boot "kernel at 1" from a new uImage at 200000 with initrd "ramdisk at 2" found in
+  some other new uImage stored at address 800000:
+bootm 200000:kernel at 1 800000:ramdisk at 2
+
+- boot "kernel at 2" from a new uImage at 200000, with initrd "ramdisk at 1" and FDT
+  "fdt at 1", both stored in some other new uImage located at 800000:
+bootm 200000:kernel at 1 800000:ramdisk at 1 800000:fdt at 1
+
+- boot kernel "kernel at 2" with initrd "ramdisk at 2", both stored in a new uImage
+  at address 200000, with a raw FDT blob stored at address 600000:
+bootm 200000:kernel at 2 200000:ramdisk at 2 600000
+
+- boot kernel "kernel at 2" from new uImage at 200000 with FDT "fdt at 1" from the
+  same new uImage:
+bootm 200000:kernel at 2 - 200000:fdt at 1
+
+
+Note on current image address
+-----------------------------
+
+When bootm is called without arguments, the image at current image address is
+booted. The current image address is the address set most recently by a load
+command, etc, and is by default equal to CFG_LOAD_ADDR. For example, consider
+the following commands:
+
+tftp 200000 /tftpboot/kernel
+bootm
+Last command is equivalent to:
+bootm 200000
+
+In case of the new uImage argument syntax, the address portion of any argument
+can be omitted. If <addr3> is omitted, then it is assumed that image at
+<addr2> should be used. Similarly, when <addr2> is omitted, is is assumed that
+image at <addr1> should be used. If <addr1> is omitted, it is assumed that the
+current image address is to be used. For example, consider the following
+commands:
+
+tftp 200000 /tftpboot/uImage
+bootm :kernel at 1
+Last command is equivalent to:
+bootm 200000:kernel at 1
+
+tftp 200000 /tftpboot/uImage
+bootm 400000:kernel at 1 :ramdisk at 1
+Last command is equivalent to:
+bootm 400000:kernel at 1 400000:ramdisk at 1
+
+tftp 200000 /tftpboot/uImage
+bootm :kernel at 1 400000:ramdisk at 1 :fdt at 1
+Last command is equivalent to:
+bootm 200000:kernel at 1 400000:ramdisk at 1 400000:fdt at 1

+How to use images in the new image format
+=========================================
+
+Author: Bartlomiej Sieka <tur@semihalf.com>
+
+
+Overview
+--------
+
+The new uImage format allows more flexibility in handling images of various
+types (kernel, ramdisk, etc.), it also enhances integrity protection of images
+with sha1 and md5 checksums.
+
+Two auxiliary tools are needed on the development host system in order to
+create an uImage in the new format: mkimage and dtc, although only one
+(mkimage) is invoked directly. dtc is called from within mkimage and operates
+behind the scenes, but needs to be present in the $PATH nevertheless. It is
+important that the dtc used has support for binary includes -- refer to
+www.jdl.com for its latest version. mkimage (together with dtc) takes as input
+an image source file, which describes the contents of the image and defines
+its various properties used during booting. By convention, image source file
+has the ".its" extension, also, the details of its format are given in
+doc/source_file_format.txt. The actual data that is to be included in the
+uImage (kernel, ramdisk, etc.) is specified in the image source file in the
+form of paths to appropriate data files. The outcome of the image creation
+process is a binary file (by convention with the ".itb" extension) that
+contains all the referenced data (kernel, ramdisk, etc.) and other information
+needed by U-Boot to handle the uImage properly. The uImage file is then
+transferred to the target (e.g., via tftp) and booted using the bootm command.
+
+To summarize the prerequisites needed for new uImage creation:
+- mkimage
+- dtc (with support for binary includes)
+- image source file (*.its)
+- image data file(s)
+
+
+Here's a graphical overview of the image creation and booting process:
+
+image source file     mkimage + dtc               transfer to target
+        +            ---------------> image file --------------------> bootm
+image data files(s)
+
+
+Example 1 -- old-style (non-FDT) kernel booting
+-----------------------------------------------
+
+Consider a simple scenario, where a PPC Linux kernel built from sources on the
+development host is to be booted old-style (non-FDT) by U-Boot on an embedded
+target. Assume that the outcome of the build is vmlinux.bin.gz, a file which
+contains a gzip-compressed PPC Linux kernel (the only data file in this case).
+The uImage can be produced using the image source file examples/kernel.its
+(note that kernel.its assumes that vmlinux.bin.gz is in the current working
+directory; if desired, an alternative path can be specified in the kernel.its
+file). Here's how to create the image and inspect its contents:
+
+[on the host system]
+$ mkimage -f kernel.its kernel.itb
+DTC: dts->dtb  on file "kernel.its"
+$
+$ mkimage -l kernel.itb

+files: vmlinux.bin.gz (Linux kernel) and target.dtb (FDT blob). The uImage can
+be produced using image source file examples/kernel_fdt.its like this (note
+again, that both prerequisite data files are assumed to be present in the
+current working directory -- image source file kernel_fdt.its can be modified
+to take the files from some other location if needed):

+U-boot new uImage source file format (bindings definition)
+==========================================================
+
+Author: Marian Balakowicz <m8@semihalf.com>
+
+1) Introduction
+---------------
+
+Evolution of the 2.6 Linux kernel for embedded PowerPC systems introduced new
+booting method which requires that hardware description is available to the
+kernel in the form of Flattened Device Tree.
+
+Booting with a Flattened Device Tree is much more flexible and is intended to
+replace direct passing of 'struct bd_info' which was used to boot pre-FDT
+kernels.
+
+However, U-boot needs to support both techniques to provide backward
+compatibility for platforms which are not FDT ready. Number of elements
+playing role in the booting process has increased and now includes the FDT
+blob. Kernel image, FDT blob and possibly ramdisk image - all must be placed
+in the system memory and passed to bootm as a arguments. Some of them may be
+missing: FDT is not present for legacy platforms, ramdisk is always optional.
+Additionally, old uImage format has been extended to support multi sub-images
+but the support is limited by simple format of the legacy uImage structure.
+Single binary header 'struct image_header' is not flexible enough to cover all
+possible scenarios.
+
+All those factors combined clearly show that there is a need for new, more
+flexible, multi component uImage format.
+
+
+2) New uImage format assumptions
+--------------------------------
+
+a) Implementation
+
+Libfdt has been selected for the new uImage format implementation as (1) it
+provides needed functionality, (2) is actively maintained and developed and
+(3) increases code reuse as it is already part of the U-boot source tree.
+
+b) Terminology
+
+This document defines new uImage structure by providing FDT bindings for new
+uImage internals. Bindings are defined from U-boot perspective, i.e. describe
+final form of the uImage at the moment when it reaches U-boot. User
+perspective may be simpler, as some of the properties (like timestamps and
+hashes) will need to be filled in automatically by the U-boot mkimage tool.
+
+To avoid confusion with the kernel FDT the following naming convention is
+proposed for the new uImage format related terms:
+
+FIT	- Flattened uImage Tree
+
+FIT is formally a flattened device tree (in the libfdt meaning), which
+conforms to bindings defined in this document.
+
+.its	- image tree source
+.itb	- image tree blob
+
+c) Image building procedure
+
+The following picture shows how the new uImage is prepared. Input consists of
+image source file (.its) and a set of data files. Image is created with the
+help of standard U-boot mkimage tool which in turn uses dtc (device tree
+compiler) to produce image tree blob (.itb).  Resulting .itb file is is the
+actual binary of a new uImage.
+
+
+tqm5200.its
++
+vmlinux.bin.gz     mkimage + dtc               xfer to target
+eldk-4.2-ramdisk  --------------> tqm5200.itb --------------> bootm
+tqm5200.dtb                          /|\
+...                                   |
+                                 'new uImage'
+
+	- create .its file, automatically filled-in properties are omitted
+	- call mkimage tool on a .its file
+	- mkimage calls dtc to create .itb image and assures that
+	  missing properties are added
+	- .itb (new uImage) is uploaded onto the target and used therein
+
+
+d) Unique identifiers
+
+To identify FIT sub-nodes representing images, hashes, configurations (which
+are defined in the following sections), the "unit name" of the given sub-node
+is used as it's identifier as it assures uniqueness without additional
+checking required.
+
+
+3) Root node properties
+-----------------------
+
+Root node of the uImage Tree should have the following layout:
+
+/ o image-tree
+    |- description = "image description"
+    |- timestamp = <12399321>
+    |- #address-cells = <1>
+    |
+    o images
+    | |
+    | o img at 1 {...}
+    | o img at 2 {...}
+    | ...
+    |
+    o configurations
+      |- default = "cfg at 1"
+      |
+      o cfg at 1 {...}
+      o cfg at 2 {...}
+      ...
+
+
+  Optional property:
+  - description : Textual description of the uImage
+
+  Mandatory property:
+  - timestamp : Last image modification time being counted in seconds since
+    1970-01-01 00:00:00 - to be automatically calculated by mkimage tool.
+
+  Conditionally mandatory property:
+  - #address-cells : Number of 32bit cells required to represent entry and
+    load addresses supplied within sub-image nodes. May be omitted when no
+    entry or load addresses are used.
+
+  Mandatory node:
+  - images : This node contains a set of sub-nodes, each of them representing
+    single component sub-image (like kernel, ramdisk, etc.). At least one
+    sub-image is required.
+
+  Optional node:
+  - configurations : Contains a set of available configuration nodes and
+    defines a default configuration.
+
+
+4) '/images' node
+-----------------
+
+This node is a container node for component sub-image nodes. Each sub-node of
+the '/images' node should have the following layout:
+
+ o image at 1
+   |- description = "component sub-image description"
+   |- data = /incbin/("path/to/data/file.bin")
+   |- type = "sub-image type name"
+   |- arch = "ARCH name"
+   |- os = "OS name"
+   |- compression = "compression name"
+   |- load = <00000000>
+   |- entry = <00000000>
+   |
+   o hash at 1 {...}
+   o hash at 2 {...}
+   ...
+
+  Mandatory properties:
+  - description : Textual description of the component sub-image
+  - type : Name of component sub-image type, supported types are:
+    "standalone", "kernel", "ramdisk", "firmware", "script", "filesystem",
+    "fdt".
+  - data : Path to the external file which contains this node's binary data.
+  - compression : Compression used by included data. Supported compressions
+    are "gzip" and "bzip2". If no compression is used compression property
+    should be set to "none".
+
+  Conditionally mandatory property:
+  - os : OS name, mandatory for type="kernel", valid OS names are: "openbsd",
+    "netbsd", "freebsd", "4_4bsd", "linux", "svr4", "esix", "solaris", "irix",
+    "sco", "dell", "ncr", "lynxos", "vxworks", "psos", "qnx", "u_boot",
+    "rtems", "artos", "unity".
+  - arch : Architecture name, mandatory for types: "standalone", "kernel",
+    "firmware", "ramdisk" and "fdt". Valid architecture names are: "alpha",
+    "arm", "i386", "ia64", "mips", "mips64", "ppc", "s390", "sh", "sparc",
+    "sparc64", "m68k", "nios", "microblaze", "nios2", "blackfin", "avr32",
+    "st200".
+  - entry : entry point address, address size is determined by
+    '#address-cells' property of the root node. Mandatory for for types:
+    "standalone" and "kernel".
+  - load : load address, address size is determined by '#address-cells'
+    property of the root node. Mandatory for types: "standalone" and "kernel".
+
+  Optional nodes:
+  - hash at 1 : Each hash sub-node represents separate hash or checksum
+    calculated for node's data according to specified algorithm.
+
+
+5) Hash nodes
+-------------
+
+o hash at 1
+  |- algo = "hash or checksum algorithm name"
+  |- value = [hash or checksum value]
+
+  Mandatory properties:
+  - algo : Algorithm name, supported are "crc32", "md5" and "sha1".
+  - value : Actual checksum or hash value, correspondingly 4, 16 or 20 bytes
+    long.
+
+
+6) '/configurations' node
+-------------------------
+
+The 'configurations' node is optional. If present, it allows to create a
+convenient, labeled boot configurations, which combine together kernel images
+with their ramdisks and fdt blobs.
+
+The 'configurations' node has has the following structure:
+
+o configurations
+  |- default = "default configuration sub-node unit name"
+  |
+  o config at 1 {...}
+  o config at 2 {...}
+  ...
+
+
+  Optional property:
+  - default : Selects one of the configuration sub-nodes as a default
+    configuration.
+
+  Mandatory nodes:
+  - configuration-sub-node-unit-name : At least one of the configuration
+    sub-nodes is required.
+
+
+7) Configuration nodes
+----------------------
+
+Each configuration has the following structure:
+
+o config at 1
+  |- description = "configuration description"
+  |- kernel = "kernel sub-node unit name"
+  |- ramdisk = "ramdisk sub-node unit name"
+  |- fdt = "fdt sub-node unit-name"
+
+
+  Mandatory properties:
+  - description : Textual configuration description.
+  - kernel : Unit name of the corresponding kernel image (image sub-node of a
+    "kernel" type).
+
+  Optional properties:
+  - ramdisk : Unit name of the corresponding ramdisk image (component image
+    node of a "ramdisk" type).
+  - fdt : Unit name of the corresponding fdt blob (component image node of a
+    "fdt type").
+
+The FDT blob is required to properly boot FDT based kernel, so the minimal
+configuration for 2.6 FDT kernel is (kernel, fdt) pair.
+
+Older, 2.4 kernel and 2.6 non-FDT kernel do not use FDT blob, in such cases
+'struct bd_info' must be passed instead of FDT blob, thus fdt property *must
+not* be specified in a configuration node.
+
+
+8) Examples
+-----------
+
+Please see examples/*.its for actual image source files.

This patch looks broken to me. You should keep the brace on the  same
line  with  the  if,  and rather delete the next line with the single
brace.

[U-Boot-Users] [PATCH 02/20] [new uImage] Add support for new uImage format to mkimage tool

[Luigi 'Comio' Mantellini]

Hi A,

I'm trying to use the newimage patches but I cannot compile the mkimage
tool because the uint8_t uint16_t, ... types are not defined into the
fdt.h include file (that uses them).
I just patched the fdt.h source adding the following code in the head:

#ifndef __KERNEL__
typedef          unsigned char   uint8_t;
typedef          unsigned short  uint16_t;
typedef          unsigned int    uint32_t;
typedef          unsigned long long int  uint64_t;
#else
#include <linux/types.h>
#endif

This is just a dirty approach... but it can be useful for who have the
same problem. Anyway, can you correct the include/fdt.h source (or the
tool/mkimage.c) to avoid this issue?

Thanks a lot,

luigi

Hmm, I've not seen this. How are you trying to compile mkimage? What 
system are you on?

I usually compile mkimage by configuring the build for any board, and
then compiling just the tools directory. Could you try this:
make TQM5200_config
make tools

BTW: "make tools" without prior make *_config says "make: Nothing to be
done for `tools'." -- can somebody offer a suggestions on how to fix this?
