[ARM] 3383/3: ixp2000: ixdp2x01 platform serial conversion
Patch from Lennert Buytenhek Add a PLAT8250_DEV_PLATFORM2, and convert the two ixdp2x01 CPLD serial ports to use platform serial devices with ids PLAT8250_DEV_PLATFORM[12]. (The on-chip xscale UART is PLAT8250_DEV_PLATFORM, id #0.) Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
