Log: Fix up NVRAM settings for boot-device and boot-args.
This patch originally started as a fix for PPC, in that the NVRAM initialiser wasn't been run on startup (this is why printenv on PPC always showed much much less than on SPARC). However, it also showed up some inconsistent logic for boot device selection, which must also happen *before* boot is called in order for load to work correctly. With this patch applied, bootpath and bootargs are set from boot-device and boot-args respectively on startup for SPARC32, SPARC64 and PPC.
Note: there is a small chance SPARC32 may break on some images - please let me know if it does.
Yes, it broke Sparc32 boot from CD: qemu-system-sparc -boot d -cdrom debian-40r4a-sparc-netinst.iso -L . -nographic Configuration device id QEMU version 1 machine id 32 UUID: 00000000-0000-0000-0000-000000000000 CPUs: 1 x FMI,MB86904 Welcome to OpenBIOS v1.0 built on Jun 28 2010 14:18 Type 'help' for detailed information [sparc] Booting file 'disk' with parameters '' Trying disk (disk) Can't read ELF header Can't read Linux header Can't read a.out header Trying disk:d (disk:d) Can't read ELF header Can't read Linux header Can't read a.out header Unsupported image format

It looks like OpenBIOS tries to boot from disk, not CD.
Could you please try to avoid committing broken patches? At the minimum, you should test that all of Sparc32, Sparc64 and PPC still boot.
