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.

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