Hi all, This series updates the Microchip PolarFire SoC (MPFS) mailbox driver in U-Boot.
The first three patches contain a set of bug fixes and cleanups to the existing driver, fixing MMIO size calculations, and removing invalid mailbox channel and private-data handling. These changes are independent of any devicetree updates and fix issues present in the legacy driver. The final patch adds support for the corrected, syscon-based devicetree bindings for the MPFS mailbox. Linux has moved to this binding to more accurately model the hardware, and U-Boot already supports the same approach for the MPFS clock controller. This patch updates the mailbox driver accordingly, while retaining support for the legacy binding for backwards compatibility. The final patch is required ASAP as boot is currently broken on master for MPFS generic boards. Tested on a PolarFire SoC Icicle Kit ES.
