It's a bit unclear to me which processor is actually in there, but I
believe it's an 8000, so it and the firmware may in fact support
PDC_BTLB_INSERT, which means that the kernel might work properly.
I have a C3000 which does *NOT* implement PDC_BTLB functions.
It sounds like the error message is actually a bit misleading.
mprintf("Looks like there's no BTLB on this box, so it's > probably\n"
"either PA1.0 or PA2.0. In any case we're screwed for now\n");
it should be:
"Looks like there's no BTLB on this box, so it's either a PA1.0 or a PA2.0
that doesn't implement BTLBs"
How far does it actually boot though?
