Hello all,
I have a question regarding LEON SPARC SMP. In a LEON SPARC SMP system
secondary CPUs (others that CPU#0) can be started by setting certain
bits in the interrupt controller. At startup (reset) all CPUs are halted
except CPU#0. In QEMU version 0.12 it was possible to simply set

This patch adds SMP support to the LEON SPARC interrupt controller.
I don't like that CPU status (halted/not halted) is accessed directly
from the interrupt controller. How can this be implemented more elegant?
Ideally the CPUSPARCState should not be accessed directly.

This patch adds SPARC ASI mappings that are used by the LEON processor.It also
corrects the MMU context register and context table pointer mask of the LEON3.
