[Qemu-devel] [PATCH 2/2] sm501: Add some more unimplemented registers

[Qemu-devel] [PATCH 2/2] sm501: Add some more unimplemented registers

[BALATON Zoltan]

These are not really implemented (just return zero or default values)
but add these so guests accessing them can run.

[Qemu-devel] [PATCH 0/2] More SM501 improvements

[BALATON Zoltan]

Two simple patches to add some more registers that were found to be
accessed by some guests.
