[OpenBIOS] Sparc32 boots Linux...

[Blue Swirl]

The loading error happened because Forth stack was in the middle of the 
kernel file being loaded. I moved it away.

Now, with an ELF kernel file as -hda:

2 > boot disk
[sparc] Booting file 'disk' with parameters '<NULL>'
Unknown filesystem type
Loading image...
segment 0 addr:0x0 file:0x2780e0 mem:0x2a3828 loading... clearing... 
clearing checksum... ok
Loaded 2588896 bytes
entry point is 0x4000
Jumping to entry point...
halt, power off

Looking at /tmp/qemu.log we find that Linux mapped itself to 0xf0000000, 
called a few Openprom functions and because of the bad results decided to 
halt.

Now we need to implement the Openprom functions for browsing the device tree 
and others in romvec.c. For example, the sequence Linux uses to find root 
node properties is something like:

node = nextnode(0); // get handle for "/"
ok = getprop(node, NULL, &str); // str should be the first property, for 
example "compatible"

How can I get this kind of handles from C?

It would be nice to get booting by loading boot sectors working so that 
instead of Linux we can try SILO.
