- Thank you so much... The reason for the chipmem move is to make loading simple.
- The kernel is loaded into chipmem, so PA==KVA, then it's copied into the part
- of available fastmem, and the MMU is turned on to map it back to KVA=0. The
- approach makes relocating kernels unnecessary (the Amix way), you don't have
- to play mean games with the MMU when booting BSD until you have the final
- tables installed, and you don't have to fiddle with manual relocation in the
- loader either. Looks like clear benefits for the current solution.
