[Qemu-devel] [PATCH 02/19] uninorth: remove second set of uninorth token registers
Posted by Mark Cave-Ayland 7 years, 11 months ago
Commit 593c181160: "PPC: Newworld: Add second uninorth control register set"
added a second set of uninorth registers at 0xf3000000.

Testing MacOS 9.2 to MacOS X 10.4 reveals no accesses to this address and I
can't find any reference to it in Apple's Core99.cpp source so I'm assuming
that this was the result of another bug that has now been fixed.
