ENGR00319772 iMX6SX:ARM2: Add EIM-NOR support for 17x17 ARM2 board
The NOR flash PC28F00AG18 has 512 of 256KB erase blocks which are locked after power on reset. Change the 17x17 ARM2 configurations to match the flash parameters, and enable the CONFIG_SYS_FLASH_PROTECTION to allow write to the flash. The EIM-NOR on 17x17 ARM2 board uses MUXed mode. This has less effort on board rework. When boot from EIM-NOR, set SW8, SW7, SW5 to all off. Signed-off-by: Ye.Li <B37916@freescale.com>
