[U-Boot] [PATCH v4 00/30]

[U-Boot] [PATCH v4 00/30]

[Franklin S Cooper Jr]

This patchset adds support for the new Keystone 2 Industrial Communication
Engine board.

This patchset includes the introduction of embedded FIT images in U-boot.
This creates a FIT image of dtb files that enables board specific code to
select which DTB to use at runtime. Initially during boot a generic DTB is
required that enables board detection to occur and once it has can later be
swapped out for the correct dtb.

Version 4 changes:
Rebased on top of master.
Tweaks done to patches 2 and 3 since functions have been added and tweaked
in spl_fit.c.
Left reviewed by as is since changes weren't drastic.

Version 3 changes:
Fixed minor comments that were missed in rev 2.

Version 2 changes:
Some patches were dropped since equivalent changes have already be
incorporated in upstream already.

The addition davinci i2c device model in upstream resulted in some
patches having to be added or tweaked.

The DT for K2G ICE is based on the version that has been accepted into
Linux mainline https://lkml.org/lkml/2017/5/22/28

[U-Boot] [PATCH v4 01/30] ti: common: board_detect: Allow settings board detection variables manually

[Franklin S Cooper Jr]

From: Nishanth Menon <nm@ti.com>

In some situations the EEPROM used for board detection may not be
programmed or simply programmed incorrectly. Therefore, it may be
necessary to "simulate" reading the contents of the EEPROM to set
appropriate variables used in the board detection code.

This may also be helpful in certain boot modes where doing i2c reads
may be costly and the config supports running only a specific board.

[U-Boot] [PATCH v4 02/30] spl: fit: Break out some functions into a common file

[Franklin S Cooper Jr]

Some of the functions within spl_fit will be used for non spl purposes.
Instead of duplicating functions simply break the functions to be reused
into its own file.

[U-Boot] [PATCH v4 03/30] boot_fit: Create helper functions that can be used to select DTB out of FIT

[Franklin S Cooper Jr]

Some platforms may append a FIT image to the U-boot image. This function
aids in parsing the FIT image and selecting the correct DTB at runtime.

[U-Boot] [PATCH v4 04/30] fdt: Enable selecting correct DTB from appended FIT Image

[Franklin S Cooper Jr]

This patch gives U-boot the runtime support to have the board specific
code decide which FDT to use. This is especially useful for devices
that need this type of runtime determination and also doesn't use SPL.

[U-Boot] [PATCH v4 05/30] ti: common: board_detect: Add function to determine if EEPROM was read

[Franklin S Cooper Jr]

When the EEPROM is first read its contents are stored in memory as a
cache to avoid further I2C operations. To determine if the EEPROM was
previously read the easiest way is to check the memory to see if the
EEPROM's magic header value is set. Create a new function that can
determine if the EEPROM was previously read or not without having to
perform a I2C transaction.

[U-Boot] [PATCH v4 09/30] board_f: Add new function to allow runtime DTB selection

[Franklin S Cooper Jr]

Runtime U-boot dtb selection is generally a two step process. First step
is to simply use an initial generic dtb. The second step is to select
the dtb and perhaps execute additional code ones U-boot knows what board
it is running on. Embedded_dtb_select handles the second step by allowing
board specific code to run and perform what ever necessary configuration
that is needed.

[U-Boot] [PATCH v4 12/30] ARM: k2g: Define embedded_dtb_select for runtime DTB selection in U-boot

[Franklin S Cooper Jr]

For K2G, runtime DTB selection utilizes the embedded_dtb_select function.
Therefore, define the function which will perform a EEPROM read and then
retries selecting the correct dtb now that it can detect which board its
on. For other Keystone devices use an empty function since they will still
use the embedded FIT functionality but their FIT will only contain a single
dtb.

Most production K2G boards do not have their EEPROM programmed. Therefore,
perform a test to verify a K2G GP is currently being used and if it is then
set the values normally set by a EEPROM read.

[U-Boot] [PATCH v4 14/30] ks2_evm: Add EEPROM based board detection

[Franklin S Cooper Jr]

Some K2G evms have their EEPROM programming while most do not. Therefore,
add EEPROM board detection to be used as the default method and fall back
to the alternative board detection when needed.

Also reorder board configuration. Perform bare minimal configuration
initially since board detection hasn't ran. Finish board configuration
once the board has been identified.

[U-Boot] [PATCH v4 17/30] ARM: k2g: Program DDR PHY MR2 register with the default value

[Franklin S Cooper Jr]

K2G GP doesn't require the MR2 register to be programed since the
default is good enough. However, newer K2G boards do need to change
this register value. Therefore, instead of not writing this register if
ran on a K2G board just program the value to be written to match the
default/reset value.

[U-Boot] [PATCH v4 20/30] ARM: k2g: Add pinmux support for K2G ICE evm

[Franklin S Cooper Jr]

Add basic pinmux data for new K2G ICE evm. Also add pinmuxing for a
generic K2G evm which includes I2C 0 and 1 used for board detection
purposes.

Since multiple K2G boards are supported that means initially generic
pinmuxing should be used when board detection hasn't ran. Once board
detection runs the proper pinmuxing can be reran to match the board
being ran on.

[U-Boot] [PATCH v4 25/30] ARM: dts: keystone-k2g: Remove skeleton.dtsi

[Franklin S Cooper Jr]

Adding the unit address to the memory node was causing the below error:
Warning (reg_format): "reg" property in /memory has invalid length
(8 bytes) (#address-cells == 2, #size-cells == 2)

Further debugging showed that this was due to the memory node added by
default to skeleton.dtsi which was being included in keystone-k2g.dtsi.
Adding a missing node was all that was needed to remove this deprecated
dtsi file from the SoC dtsi. With skeleton.dtsi removed the dtc compiler
no longer complained about including the unit address for the memory node.

[U-Boot] [PATCH v4 29/30] ARM: k2g: Add K2G ICE DTB to the list of possible DTBs

[Franklin S Cooper Jr]

K2G ICE evm will have its own dtb. Therefore, add it to the list of dtbs
located in the appended U-boot dtb FIT image. Therefore, when swapping out
dtbs K2G ICE boards can grab the correct one.
