8250 Serial Driver: Added support for 8250-class UARTs in HV Sistemas H8606 board
Added support for 8250-class UARTs in HV Sistemas H8606 board, modification in 8250.c driver for correct compilation with Blackfin Besides, I think that there is more people using 8250-class UARTs with a different hardware than the H8606 board. This code can be shared by them. Signed-off-by: Javier Herrero <jherrero@hvsistemas.es> Acked-by: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Bryan Wu <cooloney@kernel.org>
