[Qemu-devel] [PATCH] target-arm: implement CPACR register logic

2014-05-16 Thread Fabian Aggeler
From: Sergey Fedorov CPACR register allows to control access rights to coprocessor 0-13 interfaces. Bits corresponding to unimplemented coprocessors should be RAZ/WI. QEMU implements only VFP coprocessor on ARMv6+ targets. So only cp10 & cp11 bits are writable. Signed-off-by: Sergey Fedorov Sig
