[OpenBIOS] [PATCH 0/9] Milax (OpenSolaris) bringup patchset

[Mark Cave-Ayland]

Following on from the previous work, this patchset gets tantalisingly
close to bringing up a 64-bit Milax (OpenSolaris) kernel under
qemu-system-sparc64:


$ ./qemu-system-sparc64 -bios openbios-builtin.elf.nostrip -cdrom milax032sparc.iso -nographic -boot d -m 256
OpenBIOS for Sparc64

Sadly at this point the console (and eventually QEMU) lock up hard which
suggests an emulation bug hiding away somewhere, and I do occasionally
see intermittent kernel panics on boot.

Having said that, this is still a significant milestone :)
