I tested this by faking out this assemble code with no change in
behaviour. In particular:
* commented out the body of the secureworld_exit (not relevant)
* hardcoded the cpuid for get_cpu_id
* pretended to be in SRAM for get_base
I agree it seems a bit odd to have assembly inlined without explicitly
switching between ARM and thumb mode but my knowledge of interworking
is pretty limited. FWIW, an objdump --special-syms just shows ARM
mode as far as I can see.
I suspect testing u-boot v2015.07 on another OMAP35xx platform besides
Overo will be most useful to confirm the scope of the problem. Anyone
have a board and willing to test? I'm happy to send binaries :).
