OK, no extra output of current next with CONFIG_DEBUG_VIRTUAL=y.
Booting of n900 hangs with just the same error:
save_secure_sram() returns 0000ff02
> If it doesn't help, is there a way to test n900 configuration in QEMU?
I doubt that QEMU n900 boots in secure mode but instead shows
the SoC as general purpose SoC. If so, you'd have to patch the
omap3_save_secure_ram_context() to attempt to save secure RAM
context in all cases. If that works then debugging with any
omap3 board like beagleboard in QEMU should work.

Tony
