By default ZynqMP machines are setup to use PSCI for cpu bringup (QEMU
has a PSCI implementation in-built), which means you will have to load
some firmware before the kernel to handle PSCI calls, etc. ARM Trusted
Firmware is what Xilinx recommends and they provide support for.

The u-boot post regarding SPL
(http://lists.denx.de/pipermail/u-boot/2016-May/254902.html) has info
for booting atf. By default meta-xilinx will build an ATF binary for
ZynqMP targets.

Regards,
Nathan
