Override -march setting for tegra to -march=armv4t for cmd_nvedit.c 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 is a call to getenv_ulong() that causes an illegal instruction exception if cmd_nvedit is compiled for armv7.
