2026-08-05rng: add Microchip PolarFire SoC hardware RNG driverJamie Gibbons
Add a U-Boot RNG driver for Microchip's PolarFire SoC (MPFS). The hardware RNG is accessed indirectly via the MPFS system controller using the mailbox interface. The driver implements the UCLASS_RNG interface, requesting random data from the system controller and returning it to the caller. This allows use of the PolarFire SoC hardware RNG via the standard 'rng' command and DM RNG API. Signed-off-by: Jamie Gibbons <[email protected]> Reviewed-by: Leo Yu-Chi Liang <[email protected]>
