[U-Boot] [PATCH v3 16/19] sunxi: enable automatic FIT build for 64-bit SoCs

[Andre Przywara]

The Allwinner SoCs with 64-bit cores use an ARM Trusted Firmware binary,
which needs to be loaded alongside U-Boot proper.
Set the respective Kconfig options to let them select this feature and
also automatically build the FIT image.
