[PATCH v2 0/7] Microchip PolarFire SoC support

[Padmarao Begari]

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
5d92dacbbe8a751e95f0ad0cf7c3d2370e9a04c7

All drivers namely: NS16550 Serial, Microchip clock,
Cadence eMMC and Cadence MACB Ethernet work fine on actual
Microchip PolarFire SoC Icicle Kit.

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
