IMHO this HRCW value is incompatible with MPC8272 (reserved fields are not cleared, for example). Read the chip's manual to find correct values (or copy them from BCSR-supplied HRCW).

This is unnecessary because lowboot_config takes care of TEXT_BASE.

Probably because your BDI configuration file tries to use default IMMR 0x0F000000 while in fact the IMMR is 0xF0000000 due to the HRCW.

See above.
