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 c15f44acf9d473f4682bfdc63b8aebd313492b15
All drivers namely: NS16550 Serial, Microchip clock, Cadence eMMC and Cadence MACB Ethernet work fine on actual Microchip PolarFire SoC Icicle Kit.
Changes in v7: - Allocate memory using auto-alloc feature in the clock driver - Re-order header files in the clock driver - Add comments in the clock driver
Changes in v6: - Update MACB driver for 32-bit/64-bit DMA based on struct mac_config - Rename microchip,mpfs-clock.h to microchip-mpfs-clock.h - Add dual-license GPL or MIT in the clock dt-binding - Move refclk device tree node under / device tree node - Remove the dtc warnings - Fix some typos in device tree and doc
Changes in v5: - Replace compatible string "microchip,polarfire-soc" with "microchip,mpfs-icicle-kit" in the device tree - Use "mpfs" as identifier in place of "polarfire-soc", "pfsoc" - Fix some typos in doc - Rename the clock driver files clk_pfsoc_* to mpfs_clk_* - Rename pfsoc-clock.h to mpfs-clock.h
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
