This version of ATF is incompatible with the 2.27 version of binutils
that oe-core/poky provides. The following error occurs during atf
build.

...
|   AS      plat/arm/common/aarch64/arm_helpers.S
|   AS      drivers/cadence/uart/cdns_console.S
|   AS      plat/common/aarch64/platform_helpers.S

This is introduced because of
https://github.com/ARM-software/arm-trusted-firmware/commit/79627dc37259781e578c47e1e63856dd0424b2a2
being backported to this Xilinx version of atf. However the use of
padding value is broken in newer binutils.

This binutils change will need to be applied to get this working
again. For reference see this atf issue
https://github.com/ARM-software/tf-issues/issues/401.

https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=7ea12e5c3ad54da440c08f32da09534e63e515ca

Since this is an actual bug fix that is applied in master of binutils
getting this backported for morty/master would be the best way to
resolve this problem.

Nathan
