ZynqMP boot: no messages from SPL other than "Debug uart enabled"

[Michal Simek]

Hi,

the issue is likely related to incorrect DDR configuration.
BSS and Malloc space are in DDR.

rev1.1 has different DDR sodimm module then rev1.0.
The change is handled by fsbl via spd detection and aligning some
parameters.

I have generated psu init from vivado 2019.2 for 1.1 revision and send
it to mailing list. I didn't test it on hw but please test it and let me
know.

Build it like this.
export DEVICE_TREE="zynqmp-zcu102-rev1.1"
make xilinx_zynqmp_virt_defconfig
make -j

Thanks,
Michal
