mpc86xx: Change early FLASH mapping to 1M at CONFIG_MONITOR_BASE_EARLY
We define CONFIG_MONITOR_BASE_EARLY to define the initial location of the bootpage in flash. Use this to create an early mapping definition for the FLASH, and change the early_bats code to use this. This change facilitates the relocation of the flash since the early mappings are no longer tied to the final location of the flash. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
