[U-Boot] [PATCH v2] Tegra: T30: Beaver board support.

[U-Boot] [PATCH v2] Tegra: T30: Beaver board support.

[Tom Warren]

Beaver is a Tegra30 board that is nearly 100% compatible w/Cardhu.
Add a Beaver build so it can begin to be differentiated, if need be.

That should probably be 0x7ff00000, since the boot ROM(?) prevents use
of the last 1MiB. This is also a bug in the kernel DT I think.

Shouldn't the SPI flash be listed there too?

The eMMC boot partitions on Beaver appear to be 1MiB not 512KiB. Hence,
I think that should be:

#define CONFIG_ENV_OFFSET	((1024 * 1024) - CONFIG_ENV_SIZE)

I should really get around to writing a patch to allow negative values
for the offset, which would be interpreted as relative to the end of the
partition, to make this automatic. It'd also help e.g. Ventana where
some boards apparently have different size boot sectors. I'll file
myself a bug for that.

BTW, did you find out if boards.cfg would allow any of this patch to be
shared with the existing Cardhu support? Ignoring that, with the above
issues fixed (assuming the SPI is DT is made to match the kernel), then
this patch,

I'll change it. Thanks.

Yeah, missed that. I'll add it, too.

OK, I'll make that change, too, for V2.

Haven't looked at modifying boards.cfg yet. I'll take a look before I post
v2.

Thanks.
