[PATCH] ppchameleon_early_serial_map hidden under #ifdef CONFIG_SERIAL_8250

[Igor Marnat]

Hello List!

Having selected PPChameleonEVB as a platform and having turned off
seral driver (CONFIG_SERIAL_8250 is not set) I got the following error
message during kernel compilation:

arch/ppc/platforms/4xx/built-in.o: In function `board_setup_arch':
: undefined reference to `early_serial_setup'


Perhaps the following patch will be ok?
