Adding device aliases helped a bit, now the system attempts to load a kernel!

Because IO is unimplemented, the ELF image is not right.

I think the next step is to make real disk I/O (which needs DVMA allocation).

Very cool! You're making really good progress! I've commited your patch to r4 in svn.
qemu-system-sparc -L . -kernel /dev/null -nographic boot arg = 0x0
Checksum invalid (ba854bc8)!
Can you check what the checksum really is

You seem to have some stuff in there that looks pretty complete..

what's dvma?

what's dvma?
HW devices access memory using device virtual memory addresses (DVMA), which I/O MMU (iommu) translates to physical addresses by using a translation page table.

Weird,.. maybe some signedness problem...
