Hello!
Ok, this is a second attempt at B&N Nook Color board file submission.
USB peripheral mode is fully operational as is serial console and
MMC/SDCard.
I threw away all the android stuff as suggested, also cleaned up
voltage regulators and removed the ones our twl chip actually
does not have (contrary to my previous beliefs).
Bye,
Oleg

Bare-bones board file, comes with serial console, gpio keys,
MMC/SDCard and USB support.

It's good that you're sending these patches, but please also:
- Add a Signed-off-by: to each patch (see item 12 of
Documentation/SubmittingPatches)
- Cc Vikram, the original author of the board file, in the patch messages
- Cc the linux-arm-kernel@lists.infradead.org mailing list

Ah, sure. Somehow I assumed this one is auto generated for the patch submitter.
(never was a problem in the past at least).
> - Cc Vikram, the original author of the board file, in the patch messages
Ok, though I am not sure he is the original author of the nook color board file
(since (C) 2008 well predates the Nook Color), the work I base this all off is
from NookColor B&N source code drop and unfortunately people that worked on it
did not identify themselves (or I don't see it) aside from just names in some
debug comments.
> - Cc the linux-arm-kernel@lists.infradead.org mailing list
Ok, I am expecting the patch will still get quite a bit of scrutiny so I'll
wait for more feedback and next submission would be conforming.
Thanks!
Bye,
Oleg

Hi,
Nook color has Ti OMAP 3621. 3621 CPU Support is not available in
current kernel, adding CPU support will be nice before board.
BN is set to release new source code in few days, taking new code as
porting base is also recommended.
Regards,
Abimanyu G

* Re: [PATCH 1/2] Initial B&N Nook Color (encore) support.

Hello!
Is there any special support needed for 3621, though?
My understanding is that's just 3630 without a "phone" part?
The .29 kernel they had only added is_omap3621 stuff that's not
called anywhere, but smartreflex code (I guess that's might be
useful to add too of course).
I know about the new code drop is coming, but I don't
expect there to be any basic stuff changes (and this board file
is coming pretty barebones right now), besides I am not so
optimistic to actually expect this patch to be merged right away,
but I am already gathering valuable feedback. ;)
BTW I saw in the archives that you are also working a port,
do you have your tree hosted anywhere?
Bye,
Oleg

Good to see that. Unfortunately you probably have to do few
more rebases on the devel-cleanup branch because of the code
consolidation effort. We'll have to wait a bit and see what
new platform code we can merge after that is all the
consolidation is sorted out.
Please also post your series with linux-arm-kernel mailing
list Cc'd. Few comments below too.
> +#include <mach/gpio.h>
This should be linux/gpio.h nowadays.
> + if(is_encore_board_evt2()) {
You should have if ( here with space.
Maybe run scripts/checkpatch.pl --strict on the patch?

For this you need to follow the instructions at www.arm.linux.org.uk.

3621 is more or less a 3630 in a different package, less pins,
0.5mm ball pitch and no PoP option.
