Shouldn't a jump to gcc 7.2 or 8 with the Retopoline patches included,
be the target given meltdown/spectre mitigations? This is going to
affect newer Arm (mvebu potentially) and atom/x86 builds - although
these use grub generally so not so much specific to uboot not
compiling.

Hey guys,
as of U-Boot v2018.01, the bootloader requires at least a GCC 6 based toolchain
for ARM targets [1]. Building will fail with GCCs prior to 6. (I.e. current
default 5.5.0)
For the Kirkwood target, I've prepared a patch to bring it to v2018.01, but
that would result
in a failed build as
