Subject: [PATCH] ppc/85xx: Introduce RESET_VECTOR_ADDRESS to handle
non-standard link address
Some board ports place TEXT_BASE at a location that would cause the
RESET_VECTOR_ADDRESS not to be at 0xfffffffc when we link. By default
we assume RESET_VECTOR_ADDRESS will be 0xfffffffc if the board doesn't
explicitly set it.
