* define new CONFIG_ARCH_MX21 (this one is currently mutually exclusive to CONFIG_ARCH_MX27, but this might change) * splits one header file. Memory definitions, interrupt sources, DMA channels are split into common part, i.MX27 specific and i.MX21 specific. * guard access to UART5/UART6, which don't exist on i.MX21 Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
