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.
https://gitlab.denx.de/u-boot/custodians/u-boot-microblaze/tree/next

Thanks,
Michal

Changes in v2:
- Check error separately - Reported by Luca
- Align ret handling
- Also handle error from mbox_recv/mbox_send
- Move pm_api_id higher - Reported by Luca
- Fix macros for header protection
- pass rex_maxlen to ipi_req - reported by Luca

  mailbox: check ops prior calling
  mailbox: allow subnode for mbox regs
  mailbox: zynqmp: ipi mailbox driver
  firmware: zynqmp: Add zynqmp-power support
  arm64: zynqmp: add firmware and mailbox node to DT
  firmware: zynqmp: get fw version with mailbox driver
  firmware: zynqmp: create firmware header
  arm64: zynqmp: use firmware driver to get version
  arm64: zynqmp: remove old fw version function
  arm64: zynqmp: probe firmware driver

Applied all. Only in this patch I have fixed dependencies to be
selected via ARCH fragment.
Because IPI driver hasn't been adopted by Versal to be able to select
IPI directly.
