Don't you still need the CFLAGS override for warmboot_avp.o here too? I
assume that a later patch will just remove it, but it'd be nice if each
patch along the way built and booted OK to, so that "git bisect" works
through this series.

At least in this patch, I don't think SOBJS is set. Does using it here
cause build issues?

In another file in this patch, that first line was the non-inverted test:

+ifeq ($(SOC),tegra20)

That seems simpler. Can we use the same here?
