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.

Signed-off-by: Kumar Gala galak@kernel.crashing.org --- * Updated to add RESET_VECTOR_ADDRESS to top level config.mk to match how we handle TEXT_BASE
