This series of patches adds preliminary/baseline support for NVIDIA's
Tegra2 Soc. Basic CPU (AVP), RAM and UART init are covered so that the
system (Harmony and/or Seaboard) can boot to the U-Boot serial prompt.
Further support (for Coretex-A9 CPU(s), USB, SD/MMC, etc.) to follow.

Hi Tom,
Nice to see support for this board

>#define MACH_TYPE_TEGRA_SEABOARD 3005
>+#define MACH_TYPE_SEABOARD 3005
I don't think this is the way it is supposed to be done.
Patches should not contain an addition to mach-types.h.
What is generally done is you ask for an ARM sync request and in the past
Tom Rix and I have updated mach-types.h.
I did this some weeks ago.
Also i think we cannot have 2 EVMs with same MACH_TYPE_
You should probably go to ARM Linux website and register as a separate EVM.
The Number you get from there should be used. I beleive you can also change the name of the
board there; assu,ing you intend to use MACH_TYPE_SEABOARD instead of MACH_TYPE_TEGRA_SEABOARD.
It usually takes a little bit of time for the mach-types to be updated in the
linux kernel. Once that is done we sync up with the kernel.
Regards,
Sandeep

Thanks, Sandeep.
As I understand it, one of our Tegra2 kernel jockeys (Allen Martin or similar) has already had the kernel version of mach-types.h updated for Seaboard - I was just attempting to use the correct #define (MACH_TYPE_SEABOARD - we dropped all of the MACH_TYPE_TEGRA_ names AFAIK) so my patch would build/boot. Of course this define doesn't matter until the kernel is booting w/the upstreamed U-Boot, which is a ways off (it boots fine here w/our private version of U-Boot based on V2010-09).
Assuming I'm correct about the Linux version of mach-types already having been updated, how do I get a sync request in? And how is that phased in to match with my patches so that it all builds/boots?
Thanks,
Tom

Hi Tom,
We keep the U-Boot in sync with what is at
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=history;f=arch/arm/tools/mach-types;h=2fea897ebeb12959415120a7c1cdcaf5d8ac8fee;hb=4162cf64973df51fc885825bc9ca4d055891c49f
I can see that the kernel does not have the updated name yet.
Since it is only required while booting a kernel,
i would just keep the old name for the time being. When the kernel has this update, we will
update U-Boot and then you will have to send in a patch to reflect this change.
In any case u mention that you have follow up patches. By the time u get all the patches
accepted, the mach-types would have been updated in the kernel and in U-boot.
Also in one of ur patches you had updates to serial driver. You will have to keep that
change in a separte patch.
Regards,
Sandeep

[Tom Warren] Hi. Sorry for top-quoting before. My comments are now in-line.
Note that I've put in a request to my IT department to remove the 'confidential information'
b.s. disclaimer that is appended to all my outgoing Outlook emails. If anyone knows how to get
Gmail to use the standard ">" reply-to quoting, I can start using my Gmail account instead.

[Tom Warren] I'm surprised, since I was told the kernel's copy had been updated.
I'll check with the kernel guys - perhaps it only went into Android's kernel, etc.

[Tom Warren] Good idea. I'll pull out the mach-types.h change in the next (V2) patch series.

[Tom Warren] Why separate? It's an integral part of adding Tegra2 support, which is what the 1st patch does.
But if that's required, then I'll change that, too, in V2.

Replying from my Gmail account until NVIDIA IT can remove the canned disclaimer.
Sorry for the top-quote - just wanted to see if Gmail would correctly
quote previous text.
If there are no other critiques or NAKs, etc., then I'll start working
on a V2 patch with
Sandeep's changes.
Thanks,
Tom

Hi,
Your Signed-off-by seems to have made its way into the subject line. It
should be moved into the email contents. A brief description of what
this patch does, what peripherals are supported, etc would be nice too.

The format of the board directory is generally board/<vendor>/<board> or
board/<board> if the vendor only plans on maintaining 1 board. If these
are nvidia-supported boards I'd think board/nvidia is the proper place
to add files board-specific files.

In powerpc-land we use io access functions to access registers, eg
in_be32(). I'm not familiar with ARM, but I'd guess they should be used
in general. Someone with ARM experience feel free to chime in here.

Instead of adding a new vol_uint typedef and making each field of this
struct vol_uint, you can make each one uint, then instantiate the
structure as volatile.
There are a mixture of lower and upper case hex digits in the comments
below too - it'd be good to be consistent.

It'd be better to either consolidate the existing definitions of
TRUE/FALSE to some place in a common header, or just use 0 and 1.

U-Boot command implementations are generally are prefixed with do_ (eg
do_md5sum). It'd be nice to pick a more descriptive function name that

There should be defines for the serial port registers in ns16550. Using
them would make it more clear what is being set up.

This block could be surrounded by #ifdef CONFIG_TEGRA2_ENABLE_UARTD to
save some space. Same with UARTA if its ever disabled. Same comment
with other areas that choose between UART A/D.

If you do need to add this typedef (which hopefully you don't), it'd
probably be better somewhere global so every board vendor doesn't have
the same chunk of code. Eg along with vu_long.

Tabs should be removed. Are the above CPU-specifc defines? If so, they
should be moved somewhere cpu-specific so other board vendors don't need
to define them too. Actually, looking over it again, perhaps the entire
contents of board/tegra2/ should be moved somewhere in arch/arm?

I think 1st "tegra2" above should be changed to "nvidia".

Perhaps a more descriptive name could be used? NV == non-volatile to me
at first glance, and if this is tegra2-specific maybe tegra2-common.h
would be more appropriate?

The general policy is not to undef things unless its necessary.
Assuming CONFIG_USE_IRQ isn't defined elsewhere I'd remove the above

The endif comment should be changed to match the define at the top of
