Since commit 79d75d752717 (ARM: move -march=* and -mtune= options to
arch/arm/Makefile), all the Tegra boards are broken because the SPL
is built for ARMv7.
Insert Tegra-specific code to arch/arm/Makefile to set compiler
flags for an earlier ARM architecture.
Note:
The patch for commit 79d75d752717 *was* correct when it was posted.
Notice it was written for multi .config configuration where Kconfig
set CONFIG_CPU_V7/CONFIG_CPU_ARM720T for Tegra U-Boot Main/SPL,
respectively. But, it look long until that patch was merged into
the mainline, and finally, it was overtaken by commit e02ee2548afe
(kconfig: switch to single .config configuration).

I just did build test for all the Tegra boards.
Stephen,
Could you do run-test?
Tom,
Please hold back the v2015.04 release until we confim
this problem is fixed.
