[Qemu-devel] Switch to OpenBIOS for Sparc32/64?

I'd like to replace Proll with OpenBIOS as the Qemu/Sparc32 boot prom and then develop a Sparc64 port that would finally make the Sparc64 system emulator usable.

OpenBIOS/Sparc32 has reached or exceeded the level of functionality that Proll provides: * boot from HDD and CD (several Linux distro installers work, NetBSD and Solaris in progress)
* preloaded kernel, initrd and command line support
* Forth support, which is needed for Sparc64, maybe also for other OSes than Linux on Sparc32
* graphical console and -nographic support
* SMP support

One big advantage is that OpenBIOS is actively being developed at the moment. OpenBIOS is very portable, currently x86, ppc, sparc32, and amd64 are supported. The only missing feature is TFTP boot ability, but that is in my opinion not very useful for Qemu, as you can preload the kernel.

What do you think, is the switch okay, and if so, when can this happen?
