[U-Boot] [PATCH v2 0/2] ARM: atmel: sama5d3xek: enable NOR flash support

Add NOR flash support on sama5d3xek board. Then, we can use NOR flash related command to access it.
Changes in v2: - Add CONFIG_SYS_FLASH_PROTECTION - Correct the max sector number
Bo Shen (2): ARM: atmel: sama5d3xek: add nor flash init function ARM: atmel: sama5d3xek: enable NOR flash support
