[PATCH 0/4] Update Microchip PolarFire SoC

[Padmarao Begari]

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
3724ddf157aab3bd009c1da234b9a1af1621b544

The memory device node is updated in the device tree based on
the latest FPGA reference design 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.
