[meta-xilinx] rel-v2018.1 / zcu102-zynqmp: U-boot crashes with error "fdt_root: FDT_ERR_BADMAGIC"

[Martin Lund]

Inspired by your last post I tried adding an #undef CONFIG_ARM64 in
arch/arm/lib/spl.c to force it to jump to the ATF without dropping to EL2
first. That is, to try to mimic the old hacky way of booting the ATF.

Unfortunately this hack seems to be insufficient as it gets stuck at
address 0xfffea928 so I assume the ATF has crashed ending up in a reset
vector - probably because some preconditions not being fulfilled.

In the end, perhaps the best way forward is to try use the new ATF
framework in u-boot but as you point out the information is sparse on that
point.

Hopefully someone out there can provide us with the missing information so
that we can get the zynqmp booting without using the horrible xilinx
toolchain.
