Bikeshed: I know that this matches what the Linux kernel has for 32-bit 
ARM, but I've always disliked using the word "machine" to describe an 
SoC. Would just "tegra" or "soc-tegra" be better than "mach-tegra"? Feel 
free to entirely ignore this though; I don't feel too strongly.

Oh and one more thing: We're starting to work on 64-bit Tegra support in 
the Linux kernel. A fair amount of the code moved by this patch is 
likely to apply on both 32-bit and 64-bit Tegra. Will arch/arm support 
64-bit within U-Boot, or will there be a separate directory for 32- and 
64-bit ARM? If so, should this code all be moved to something more like 
soc/tegra/... or drivers/tegra/... or drivers/soc/tegra/... or ... so it 
can be shared between the architectures?
