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

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
