This patch causes the kernel uncompressor to determine the physical address
of the SDRAM at runtime. This allows the kernel to boot on both tegra20 and
tegra30 even though SDRAM is at different physical addresses on both SoCs.

An alternative would be to simply add that config option to the relevant
defconfig/.config file. I see both cases in use in the kernel. Still, the
code change this enables looks fine to just turn on all the time, and will
be needed for Tegra30 support, so I'm fine just selecting it as you have.

P.S. Since this patch relates to Tegra, you should CC the Tegra maintainers
and list; I've done so on this message. I also added Arnd; he might take
this through the arm-soc tree.

While it does touch a file outside of arch/arm/mach-tegra, it's for
the tegra options and is not likely to cause conflicts upstream. I'll
apply it with the rest of tegra patches for 3.2 here.

So: Applied, thanks.
