arm: mvebu: helios4: Enable SPI flash support
Enable SPI flash support under U-Boot and SPL. The ENV size and offset, ported from U-Boot 2013.01 Marvell version: 2015_T1.0p16 To create U-Boot image for SPI flash, user would need to replace * CONFIG_MVEBU_SPL_BOOT_DEVICE_MMC with CONFIG_MVEBU_SPL_BOOT_DEVICE_SPI * CONFIG_ENV_IS_IN_MMC with CONFIG_ENV_IS_IN_SPI_FLASH Signed-off-by: Aditya Prayoga <aditya@kobol.io> Reviewed-by: Stefan Roese <sr@denx.de> Tested-By: Dennis Gilmore <dgilmore@redhat.com> Reviewed-By: Dennis Gilmore <dgilmore@redhat.com> Signed-off-by: Stefan Roese <sr@denx.de>
