This patch adds Microchip MPFS Icicle Kit support. For now, only NS16550 Serial, Microchip clock, Cadence eMMC and MACB drivers are enabled. The Microchip MPFS Icicle defconfig by default builds U-Boot for S-Mode because U-Boot on Microchip PolarFire SoC will run in S-Mode as payload of HSS + OpenSBI.
