This patch set adds Microchip PolarFire SoC Icicle Kit support to RISC-V U-Boot.
The patches are based upon latest U-Boot tree (https://gitlab.denx.de/u-boot/u-boot.git) at commit id 7889951d0f56eab746a7c8fde350a022ba0361ca
All drivers namely: NS16550 Serial, Microchip clock, Cadence eMMC and Cadence MACB Ethernet work fine on actual Microchip PolarFire SoC Icicle Kit.
Changes in v4:
- Add dual-license GPL or MIT in the device tree
- Replace microsemi compatible strings with microchip
- Add MACB compatible string for Microchip PolarFire SoC ethernet
- Update MACB driver for 32-bit/64-bit DMA based on compatible string
Changes in v3:
- Add 'default y if 64BIT' for config DMA_ADDR_T_64BIT
- Update MACB driver for 32-bit/64-bit DMA based on design config register
- Add phy-handle in MACB driver to read the phy address from device tree
- Fix checkpatch warnings in the clock driver
- Remove fu540 related compatible strings from soc device tree node
- Move refclk device tree node under /soc device tree node
- Use local-mac-address instead of mac-address in the device tree
- Rename device tree to microchip-mpfs-icicle-kit.dts
- Add U-Boot specific dts microchip-mpfs-icicle-kit-u-boot.dtsi file
- Drop the imply DMA_ADDR_T_64BIT from board config
- Fix some typos
- Update doc with Microchip and Custom boot-flow
Changes in v2:
- Add clock frequency for the clint device tree node
- Move peripheral device tree nodes under /soc device tree node
- Device tree nodes are in order based on the address
- Enable UART0 for U-Boot logs
- Update doc for the U-Boot logs are on UART0
- Move clock and reset index source into patch4
- Remove "dma_addr_r" type in the macb driver
- Add lower_32_bits() for 32-bit address in the macb driver
- Add set_rate() returns the new clock rate in the clock driver

Can you please rename the files clk_pfsoc_* to mpfs_clk_*? I know this naming is inconsistent but we need to start somewhere. Also pfsoc-clock.h to mpfs-clock.h.

Cyril.
