Out of curiosity, what parts did you miss?
Like, for example, the PCI stuff. So I can use the network card.
PCI stuff in the QEMU/Malta works fine, but pseudo-bootrom
does not perform PCI enumeration and leaves uninitialized PCI BARs.
Linux MIPS/Malta 2.4 can not perform PCI enumeration too. The LANCE
Ethernet driver *requres* a pre-initialized BARs. The situation even worse,
since current Linux 2.4 can't be even built with NEW_PCI and PCI_AUTO
options at all (due to linkage error).

There is the same PCI problem with NetBSD/evbmips and seems VxWorks/Malta.
Well, that's a pretty big showstopper, don't you think?

The only thing we need is a good bootrom (BIOS) for the MIPS/Malta
(Free-YAMON ;)
As a quick'n'disty solution you could initialize PCI BARs of the
device number 12 (0x0b, LANCE) with GDB:
(gdb) set variable {int}0xbbe00cf8=0x80005810 <--- I/O address
(gdb) set variable {int}0xbbe00cfc=0x00002001
(gdb) set variable {int}0xbbe00cf8=0x80005814 <--- Mem address
(gdb) set variable {int}0xbbe00cfc=0xfc200000
(gdb) set variable {int}0xbbe00cf8=0x80005804 <--- Enable Mem and I/O
(gdb) set variable {int}0xbbe00cfc=0x00000003
(gdb) set variable {int}0xbbe00cf8=0x8000583c <---- IRQ=10 tied to Pin A
(gdb) set variable {int}0xbbe00cfc=0xff06010a
(gdb) cont
Continuing.
That's dirty alright, but not exactly quick. You kind of need gdb :-)
