Also move the spi flash configurations to the at91-sama5_common.h. Current at91 zImage size is about 3.3M, the old mapping is not suitable. So update the spi flash map as following: 0x0 ~ 0x004000: at91bootstrap(16k) 0x04000 ~ 0x008000: u-boot env(16k) 0x08000 ~ 0x060000: u-boot(352k) 0x60000 ~ 0x06c000: dtb (48k) 0x6c000 ~ 0x400000: kernel (3M+592k) In AT91Bootstrap, the U-Boot in spi flash also update to 0x8000, refer to following commit in AT91Bootstrap: 3e91e54 Kconfig: fix spi flash address So also update SPL's u-boot load address to 0x8000 in spi flash.
