[OpenBIOS] fcode rom loading

[Bob Breuer]

I'm trying to get the sparc32 OpenBIOS to load an fcode rom, but it's
not working.  After byte-load, it reports out of memory.

Here's the steps I'm using to setup a simple rom which just sets the
device name to "QEMU,test", and then trying to run it:
fd000000 1000 l!
00000020 1004 l!
12095145 1008 l!
4d552c74 100c l!
65737401 1010 l!
1412046e 1014 l!
616d6501 1018 l!
10000000 101c l!
cd /iommu/sbus
" /iommu/sbus" select-dev
new-device
1000 1 byte-load

Here, OpenBIOS will report out of memory.
