I've only pushed this chunk, the rest should already be there after
git-cherry-picking following commits from arm tree:

Can you please check that these are enough? Then provide follow-up
patches if something else needs changing.

If you want more patches from arm git tree, then also provide
the commit id.

I re synched my patches with these pushes, I find 3430 kernel based de-compressing failing. Need to debug further. But u-boot based un-compression works fine. So the patch set should be sufficient. I will fix the other issue later. I tested booting on 2430 its fine too.

I will wait for your response on debug_card_init comment for 3430. I will repost all the patches again probably tomorrow.

Thanks

Khasim.

What is the correct approach for common board devices...?

[Syed Mohammed, Khasim]

Hi Tony,

There are some devices like TS, Keypad, I2C, Flash, etc that are almost common between 2430 and 3430 SDPs. 

Today in tree we have files like board-2430sdp-flash.c which can be reused for 3430 too.

The board-2430sdp.c has Keymap that holds good for 3430 too.

Can you please suggest the correct way to organize these kind of devices in mach-omap2 directory?

Regards,
Khasim

How about creating something like arch/arm/mach-omap2/sdp-common.c
for them?

OK, great.

See my previous mail for that.
