CortexA8: Introduce Freescale i.MX51 variant
This patch introduces support for Cortex A8 based Freescale i.MX51 CPU. This CPU
has the Debug Access Port located at a different address (0x60008000) than TI
OMAP3 series of CPUs.
i.MX51 configuration file based on OMAP3 configuration file and an email from
Alan Carvalho de Assis <acassis@gmail.com>.
