Hmm. Surely both or neither Whistler and Cardhu need this? Either this
isn't needed, or it's wrong in Whistler before this series.

Uggh. git format-patch is certainly being over-zealous there, and
equally failing to find the presumably much more familiar other Tegra
config files:-(

Rather than duplicating this whole file, I wonder if it wouldn't be
better to have tegra*-common.h include tegra-common.h with all the
common stuff, and factor it out.

We should remove that from tegra20-common.h

Seems like this should be the same on all Tegra.

Should LOADADDR and SYS_LOAD_ADDR match? Is only one of those useful?

Oh, how long is that used for? I hope the stack is dynamically allocated
during relocation... That (existing Tegra20) value clashes with the
ramdisk_addr_r I picked in my recent patch "ARM: tegra: use standard
variables to define load addresses".

Why not 8010c0000? Is the SPL so large it doesn't fit? I suppose it's
fine to have different SPL sizes on the two SoCs.
