Looks like it makes sense. Here is what the comment says in
arch/arm/cpu/armv7/tegra2/config.mk

# Use ARMv4 for Tegra2 - initial code runs on the AVP, which is an ARM7TDI.
PLATFORM_CPPFLAGS += -march=armv4

Even if we could fix this, Rob is adding the API for all 'arm', which I
feel is not correct.

best regards,
Aneesh
