Hi Andre,

The Pine64 (and all other 64-bit Allwinner boards) need to load an ARM Trusted Firmware image beside the actual U-Boot proper. This can now be easily achieved by using the just extended SPL FIT loading support, so enable it in the Pine64 defconfig. Also add the FIT image as a build target to 64-bit sunxi board to trigger the respective Makefile rules.

I'm not sure we want to force down that support to all our users.

A64 boards are now unusable without proper ATF.

That's debatable, but that's not really what I meant. What I meant was that they're perfectly usable without FIT.

But this is a defconfig for a certain, and the Pine64 is not really usable without ATF at the moment in an upstream tree.

Do you want a CONFIG_LOAD_ATF wrapper option, that would make it easier to select / deselect?

I will try to adapt ARMv8 PSCI on A64.

(But I don't know ARM assembly well... both 32 and 64)

Cheers, Andre.
