I don't know how the BAT works, but here are some comments on relocation:
- The kernel can be linked for the virtual address it will be finally using,
and loaded at some other physical address. Some careful hand crafted assembly
in locore.s can setup the mmu properly. This avoids the need for relocation,
but it is not trivial to write the hand crafted assembly.
- Write all the code pic? Is that even feasible?
- Use a separate magic program as you mention. Seems to me that it will
be difficult to debug...
- have an ld.so in the kernel. But then ld.so will need to relocate itself, so
you end up in the second case.
