Hi,
I've been working on Sparc32/64 support for Qemu. Currently Qemu for Sparc32 uses Proll as a system boot rom, but it's not a very good starting point for Sparc64. Basically, Linux expects a bit too much from the OpenFirmware interface, like Forth support etc.
I guess OpenBIOS would be a better choice. How complete do you think OpenBIOS is, can it boot Linux for example on some architecture? Is there any support for 64-bit architectures?
