Override -march setting for tegra to -march=armv4t for files that are necessary for low level init on tegra.
The recent change to use -march=armv7-a for armv7 caused a regression on tegra because tegra starts boot on a arm7tdmi processor before transferring control to the cortex-a9. While still executing on the arm7tdmi there are calls to getenv_ulong() and memset() that cause an illegal instruction exception if compiled for armv7.

(This seems to be necessary to use gcc-4.6.1, but not gcc-4.5.3. The Whistler patches I just sent were tested with this fix in place)
Hi Tom, could you pick this up in u-boot-tegra? Without it tegra is currently broken in both u-boot-tegra and u-boot gits depending on the compiler you use.
