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
