[U-Boot-Users] [PATCH 00/13] new uImage patchset1 - cleanup

[U-Boot-Users] [PATCH 00/13] new uImage patchset1 - cleanup

[Marian Balakowicz]

This is a first set of patches that provides a initial cleanup and code
rearrangements before the proper new uImage format implementation.

API is defined for the current (old) image related processing, and it'is being
introduced in place of the direct header access.

[new uImage] Return error on image move/uncompress overwrites
[new uImage] Cleanup image header pointer use in bootm code
[new uImage] Coding style cleanup - part 1
[new uImage] Add memmove_wd() common routine
[new uImage] Fix FDT header verification in PPC do_boot_linux() routine
[new uImage] Fix uImage header pointer use in i386 do_bootm_linux()
[new uImage] Remove I386 uImage fake_header() routine
[new uImage] Move CHUNKSZ definition to image.h
[new uImage] Move gunzip() common code to common/gunzip.c
[new uImage] Cleanup OF/FDT #if/#elif/#endif use in do_bootm_linux()
[new uImage] Move PPC do_bootm_linux() to lib_ppc/ppc_linux.c
[new uImage] Define a API for image handling operations
Add missing cmd_ximg.o to common/Makefile

Comments and suggestions are welcome.

Due to a 40K message limit, not all of the patches can be sent to ml,
oversized patches will provide a http location instead.

Cheers,
Marian

[U-Boot-Users] [PATCH 02/13] [new uImage] Define a API for image handling operations

[Marian Balakowicz]

- Add inline helper macros for basic header processing
- Move common non inline code common/image.c
- Replace direct header access with the API routines
- Rename IH_CPU_* to IH_ARCH_*

[U-Boot-Users] [PATCH 07/13] [new uImage] Remove I386 uImage fake_header() routine

[Marian Balakowicz]

I386 targets are not using a uImage format, instead fake header
is added to ram image before it is further processed by bootm.

Remove this fixup and force proper uImage use for I386.

[U-Boot-Users] [PATCH 12/13] [new uImage] Cleanup image header pointer use in bootm code

[Marian Balakowicz]

- use single image header pointer instead of a set of auxilliary variables.
- add multi component image helper routines: get component size/data address

[U-Boot-Users] [PATCH 13/13] [new uImage] Return error on image move/uncompress overwrites

[Marian Balakowicz]

Check for overwrites during image move/uncompress, return with error
when the original image gets corrupted. Report clear message to the user
and prevent further troubles when pointer to the corrupted images is passed
to do_bootm_linux routine.

What is the wisdom of the crowd, is it possible to port over the 
remaining 5 boards and removing the "CONFIG_OF_FLAT_TREE" code in this 
merge window, or is it too risky?  My gut says too risky, do it in the 
next window.

$ find . -name "*.[h]" | xargs grep CONFIG_OF_FLAT_TREE | grep 1

Fortunately, we browbeat the list admin into exercising some flexibility 
on oversize messages.  :-D

Now we have to start working him over to make the hard limit 100K with a 
soft limit of 400K to keep up with linux-ppc (and yes, that's a joke!).

When the 86xx repo is pulled by Wolfgang, the 8610 board
will be done!

The sbc8641 board is likely really easy given that I
have already done it for the Freescale MPC8641HPCN board.
I am not sure who is pushing that code around, though.

apparently you're not up to date; the sbc8349 has already been
converted over.

Ahh, you're right (blushes).

Even better!  Add in Jon's pending update and we are down to 3 boards,

Can you please comment a bit about the current state of these patches?

Is this just a RFC, or tested code?

Does the code compile? For which boards / architectures?

How much does it change the memory footprint?

Please review your patches and make sure to keep  the  original  for-
matting of the U-Boot output; for example:

--- a/common/cmd_bootm.c
+++ b/common/cmd_bootm.c
...
-			if (crc32 (0, (uchar *)data, len) != ntohl(hdr->ih_dcrc)) {
-				puts ("   Bad Data CRC\n");
-			}
-			puts ("OK\n");
+			if (!image_check_dcrc(hdr))
+				puts ("Bad Data CRC\n");

This is IMO a change to the worse. Please fix.


--- a/include/image.h
+++ b/include/image.h
...
+char *strncpy(char *dest, const char *src, size_t count);

Please don't do this! Include the appropriate header file instead.


+static inline int image_check_target_arch(image_header_t *hdr)

Theoretical thought: could it  ever  happen  that  we  might  have  a
multi-architecture image?

This is a bad name. "bootm" is more than just booting Linux images.

The ARM port did this wrong, and many others copied  the  error.  Now
let's  take  the  opportunity  and clean this up instead of making it
worse.

Please neame this lib_ppc/bootm.c or similar (ditto for the other
architectures).

Does this really work? With compressed images?

Me thinks that load_end gives a value which does not take into
account that the loaded, uncompressed image will be much bigger than
image_get_data_size() tells - or am I missing something?

Hi Wolfgang,

I agree the change is uglier.  Unfortunately, running a file through
Lindent does this.  (My personal coding style uses much more whitespace
than the Linux style, so sometimes I need to run Lindent to remove
spaces my fingers put in automatically.)

Maybe the coding style should be "run 'Lindent -pcs', then undo the
following...".  I'll admit that I'm already removing all the tabs that 
Lindent inserts before comment in the case of

#endif /* defined(FOO) */

Best regards,
Larry

It has been tested on lite5200b board. Tests covering bootm (single na
multi component images), autoscr, iminfo, imls.

> Does the code compile? For which boards / architectures?

Yes, it does. MAKEALL builds were run for ppc, mips, arm and coldfire
(although not all targets, as some of them are broken in the baseline
code). I have also attempted to build on i386, but the i386 target
builds are broken as well, I have just verified that modified files do
compile. Other architectures were skipped due to lack of the toolchains.

It would be good if other architecture maintainers could help testing
new uImage patches, as the changes are cross platform. Another good
verification would be booting OS other than linux. But, as there are
more significant changes coming, it may have more sens to wait with
the detailed tests until crucial modifications are finished.

> How much does it change the memory footprint?

Here is the build output for lite5200b_LOWBOOT configuration and with
the patches applied:

   text    data     bss     dec     hex filename
 222739   13120  305152  541011   84153 ./u-boot

Note, that patches enable DEBUG in do_bootm() and PPC variant of
do_bootm_linux(), with those disabled we get:

   text    data     bss     dec     hex filename
 222011   13080  305152  540243   83e53 ./u-boot


and the same configuration build for the 1.3.1 baseline:

   text    data     bss     dec     hex filename
 221463   13040  305408  539911   83d07 ./u-boot

[snip]

I'd be more then happy to removed CONFIG_OF_FLAT_TREE from image/bootm
related code. It'll simplify the current code and will allow to avoid
unnecessary hassle when adding new functionality.

How about I do such cleanup in the next patchset? It will not hit
mainline  before the next window and it seems we should be done with
converting remaining boards by then. Does that sound reasonable?

The baseline was "Release v1.3.1" commit, I'll rebase to current HEAD
as there are some conflicts with the latest commits.

But from the above it seems that you were attempting to apply patch
02/13 for which patch body was not posted to the ml?

Will fix.

With the new uImage that would be possible, each component image will
have it's own arch/os properties.

The above routine (handling current image format which does not allow
multi arch images) checks whether image arch matches target arch.

It is a reasonable check, running other arch images usually make
little sens. That would also apply for new uImage format, we may have
multiple component images (each for different arch) but before running
selected image we check for arch compatibility.

I see, naming seemed arbitrary, but I did not know the full story.

I'll rename all related files.

Thanks for pointing this out, will fix this.

Yes it does, I tested it with compressed linux kernel images.

That part of the patch deals with the FDT blob image. Compressed blobs
are not supported in the current code, so no decompression happens and
we can use image_get_data_size(). BTW, this particular overwrite check
is already present in the current U-boot.

thanks.

Yes, but you gave us an URL where I downloaded the missing pieces
from...

[A repository on pollux would be easier for me, of course.]
