[meta-xilinx] Ultra 96 support

[Philip Balister]

I've started looking at the Ultra 96 patches from way back and have a
few comments, all against master:


The file
meta-xilinx-bsp/recipes-microblaze/gcc/gcc-source_7.%.bbappend
b/meta-xilinx-bsp/recipes-microblaze/gcc/gcc-source_7.%.bbappend
no longer has a file to append.

A tune file has been renamed:

-require conf/machine/include/arm/arch-armv8.inc
+require conf/machine/include/arm/arch-armv8a.inc

Nothing provides:

-               virtual/pmu-firmware \


And U-boot isn't building, not sure why. This seems to be the porblem:

ake[4]: 'arch/arm/dts/zynqmp-zcu100-revC.dtb' is up to date.
test -e arch/arm/dts/zynqmp-zcu100-revC.dtb || (

                \
echo >&2;                                                       \
echo >&2 "Device Tree Source is not correctly specified.";      \
echo >&2 "Please define 'CONFIG_DEFAULT_DEVICE_TREE'";          \
echo >&2 "or build with 'DEVICE_TREE=<device_tree>' argument";  \
echo >&2;                                                       \
/bin/false)
