Hi,

This patch series using ZynqMP firmware driver to provide a interface to
communicate with the PMU Firmware. As part of the series a mailbox driver
is also implemented to handle communication through ipi interface.

There are two new wiring:
1. Reading PMUFW version via firmware driver
 - mailbox driver in case of SPL
 - SMC in case of full U-Boot
2. Using the same patch for loading PMUFW configuration object

The whole series is based on several patches I have sent already that's why
I am providing a branch which also contains this series.

Thanks,
Michal

Good to see this work going on, thanks!

I can't review in detail most of the patches, but I'm still replying
with some (mostly minor) comments.
