This patch set updates Microchip PolarFire SoC Icicle Kit support of RISC-V U-Boot.
The patches are based upon latest U-Boot tree (https://source.denx.de/u-boot/u-boot) at commit id 8bc87a4c55a1723728374a5643f13bced37dad6b
The memory device node is updated based on the latest FPGA reference design v2022.10 and a small 4MB reservation is made at the end of 32-bit DDR to provide some memory for the HSS to use, add Microchip QSPI driver.
Changes in v3: - Add reference design campatible in the device tree - Change QSPI time out value to 500ms(as per Linux) - Fix some typos
Changes in v2: - Add Co-developed-by with patch - Replace spi-nand with flash in device node - Add board details for QSPI NAND - Rename QSPI driver file with microchip-coreqspi - Add microchip,coreqspi-rtl-v2 to the compatible list - Use MICROCHIP_COREQSPI instead of MICROCHIP_QSPI in kconfig
