[ARM] 3459/1: ixp23xx: fix debug serial macros for big-endian operation
Patch from Lennert Buytenhek The debug-8250 macros do byte accesses, which means that if we're in big-endian mode, we need to logically OR the UART address with 3, as the LSB byte lane (where UART data and status is transferred) has the highest byte address in the word when we are in big-endian mode. It's unclear why this problem didn't surface earlier. Signed-off-by:Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by:
