[U-Boot-Users] [PATCH 0/7] DaVinci: Add TI DaVinci support to U-Boot

[Dirk Behme]

The following patches are a proposal to add TI DaVinci support to
U-Boot. They are completely based on ksi at koi8.net patches:

http://article.gmane.org/gmane.comp.boot-loaders.u-boot/27603
http://article.gmane.org/gmane.comp.boot-loaders.u-boot/27604
http://article.gmane.org/gmane.comp.boot-loaders.u-boot/27605

Many thanks to ksi at koi8.net for these! Following small modifications
are done:

- Make patch set apply cleanly to recent git

- Remove some #if 0 and #if 1

- Remove some (hopefully all?) compiler warnings

- Create 3 configs (DaVinci EVM, Sonata, Schmoogie) instead of one
which had to be edited to switch to another board.

- Attention: It seems that in original davinci.h config file there was
missing/incorrect configuration for Schmoogie NOR (?). Therefore I added

#define CFG_FLASH_SECT_SZ	0x20000		/* 128KB sect size AMD Flash */
#define CFG_ENV_OFFSET		(CFG_FLASH_SECT_SZ*2)

in davinci_schmoogie.h Please check if this is correct!

- The directories

cpu/arm926ejs/tms320dm6446/

and

include/asm-arm/arch-tms320dm6446

are renamed to "davinci". As both are subdirectories of "*arm*'"
directories, it is clear that they are not DSP related. I think that
"davinci" is more intuitive and less confusing

http://article.gmane.org/gmane.comp.boot-loaders.u-boot/28321

Compare omap directories, they are not called tms* as well.

- I removed usage of

include/asm-arm/arch-davinci/types.h

- I removed usage of mach-types.h. While it would be nice to have
mach-types.h, introducing mach-types.h would require all boards to
switch to use it. And this would be another task, which isn't related
to DaVinci.

As you can see, I split the patches into seven parts and attached them
unzipped. Therefore:

Please comment, improve and test!

But be aware: Deadline of U-Boot merge window is August 17, 2007:

http://article.gmane.org/gmane.comp.boot-loaders.u-boot/30437

Note #1: Default toolchain for this patches is arm-linux-*. If you use
MontaVista toolchain, you have to add

CROSS_COMPILE = arm_v5t_le-

to board/davinci/config.mk.

Note #2: Depending on your toolchain you will need the fix for
nand_util.c 64bit division

http://article.gmane.org/gmane.comp.boot-loaders.u-boot/30484
http://article.gmane.org/gmane.comp.boot-loaders.u-boot/30476

until it is merged to main branch.

Note #3: Use the following configurations to select one board:

make davinci_evm_config

or

make davinci_sonata_config

or

make davinci_schmoogie_config

Many thanks and best regards

Dirk

Wow!

My work is stolen right off my hands... Very very nice... To say I'm amazed
is to say nothing...

I'll send my modified set in a couple of hours. With all the fixes and
working Large Page NAND.
