[U-Boot] [PATCH v6 0/6] Add an SPL to boot the da850evm from SPI

[Christian Riesch]

Hi,
this is v6 of the last part of my recent patchset

[PATCH v3 00/15] Add an SPL to boot the da850evm from SPI
http://lists.denx.de/pipermail/u-boot/2011-November/111182.html

Most of the other parts are already merged, together with
this patchset they introduce an SPL for the da850evm to run
u-boot directly without the need of a UBL (see doc/README.davinci).

The first patches fix dependencies and introduce a function
to load the u-boot image from SPI flash. Patch #4 adds an
SPL to the da850evm configuration. Finally, a simple
AIS (Application Image Script) is required to start the SPL.
This AIS is generated by mkimage. Patch #5 fixes mkimage for building
AIS. Finally the last patch introduces a u-boot.ais target in the
Makefile.

Changes for v6:
- rebased to git://git.denx.de/u-boot.git master

Changes for v5:
- changed formatting (indentation) of the $(obj)u-boot.ais target in
  the Makefile
- removed useless '0 | ... ' from include/configs/da850evm.h
- added Acked-bys

Changes for v4:
- added documentation for the SPL to doc/README.davinci
- split patchset because it got too big
- use COBJS-$(CONFIG_SPL_SPI_LOAD) instead of ifdefs in
  drivers/mtd/spi/Makefile
- use __noreturn instead of __attribute__((noreturn))
- added Acked-by

Changes for v3:
- removed noise and hardcoded values from drivers/mtd/spi/spi_spl_load.c
- replaced $(PAD_TO) in Makefile by $(CONFIG_SPL_MAX_SIZE)

Major changes for v2:
- Added code that actually loads u-boot from SPI flash and starts it.

Prerequisites:
- This patchset builds fine on gcc version 4.5.2 (Sourcery G++ Lite 
  2011.03-41). However, for some toolchains, e.g., gcc 4.2.2 from
  ELDK 4.2, the build results in a linker error: "arm-linux-gnueabi-ld:
  error: no memory region specified for loadable section `.ARM.exidx'".
  In this case, the following patch is required:
  arm, davinci: Use lldiv for the 64-bit divisions in timer.c
  http://patchwork.ozlabs.org/patch/130409/

To build run
  make da850evm_config
  make u-boot.ais
Then program u-boot.ais to the SPI flash on the da850evm.

Best regards,
Christian

[U-Boot] [PATCH v6 5/6] mkimage: Fix variable length header support

[Christian Riesch]

Support for variable length images like AIS image was introduced
in commit f0662105b674a3874227316abf8536bebc9b5995. A parameter
"-s" was also introduced to prohibit copying of the image file
automatically in the main program. However, this parameter
was implemented incorrectly and the image file was copied
nevertheless.

Thanks for merging this into ti/next, Tom!

I'd like to submit a similar patch for the da850_am18xxevm board. Before
commit 06194b6b65f701a9d6ef2d9b4123c4afe57d8783 both the da850evm and the
da850_am18xxevm used the same configuration, and the differences introduced
in the commit are rather small. Should I submit a patch that adds the same
SPL configuration to the am18xx board config? Or should we create a header
file that contains the common parts and include it in both da850evm.h and
da850_am18xxevm.h? Or shall we use the Options column in boards.cfg?

I'd like it if you submitted a patch for both boards.  On my TODO list
is seeing about cleaning up some of the config files for non-omap4/5
(which have a common.h file they start with) in 2012.03.

Ok, I'll try to provide a patch for da850_am18xxevm.h, but currently I
can't get it running:

I applied the changes that I did in include/configs/da850evm.h before to
da850_am18xxevm.h as well. I expected this to work on my board since the
board I used to test the SPI flash SPL patchset for the da850evm was
actually an AM1808 experimenter's kit.

Now my SPL reports:

SF: Unsupported manufacturer 20
failed.

Manufacturer 0x20 seems to be ST and the main difference between da850evm.h
and da850_am18xxevm.h is the missing #define CONFIG_SPI_FLASH_STMICRO in
da850_am18xxevm.h.

So my question is: Which boards are supported by da850_am18xxevm.h? I
thought that I probably have an old revision of the board, but I couldn't
find anything regarding SPI flash in LogicPD's PCNs.

Thanks for your help!
Christian

So, the da850evm is for the OMAP-L138 and da850_am18xxevm is for the
AM18xx EVM.  However, the config split was done, I believe, but folks on
the L138 side and might not have been tried fully on the am1808.  So
since you've got the AM1808 and can test it there, lets add the missing
SPI_FLASH define too.  I think my coworker that did a quick non-SPL
check of the code the other week also noted SPI wasn't supported.

Ok, I can do that.

But then I wonder why a separate .h file for the AM18xx EVM was introduced.
My AM18xx EVM works just fine with the da850evm.h configuration that's
currently in mainline u-boot.

I did a diff between the two:

Pointless because of

So it could be removed.

Afaik this is used to pass the information whether this is AM1808 or

I'll add this line back because my AM1808 experimenter's kit has an ST
flash.

I don't know why these two additional lines are needed. Network works fine
with the da850evm.h config on my AM1808 experimenter's kit. Any ideas? Can
we remove these?

I have a patch in my queue that adds this line also to da850_am1808evm.h to
allow booting without the UBL (similar to commit
ae5c77dd908edaf55025fa3f41095bfb9cb1b973).

Again formatting change only.

So from my point of view it looks like we could remove the entire
da850_am18xxevm.h and just find a different way to pass the
AM1808-or-OMAP-L138 information to Linux.

[snip explanation of how little is actually different]

I agree.  It's on my list to unpack and get my am18xx EVM setup and see
if perhaps we can't just use boards.cfg to build for L138 or AM1808.
