I know present BeagleBoard doesn't boot.  OMAP3530(CORTEX-A8) supports
ARMv7.  However, you can see ARM11 support ARMv6 here.

However, ARMv7 has two TTB. It is different in OS and process.  In
addition, when the address of TTB is DOMAIN_CLIENT, it seems not to
operate correctly. However, I am not sure of should DOMAIN_MANAGER TTB.
Does anyone have this information?
On the other hand, Linux guys also defines DOMAIN_TABLE and DOMAIN_IO.
However we defined only PMAP_DOMAIN_KERNEL.

And, I am not sure of our support of neither MVA nor FCSE.
Am I wrong?

Thanks,
