Padmarao Begari0a04ad62021-01-15 08:20:41 +05309The PolarFire SoC is the 4+1 64-bit RISC-V SoC from Microchip.
10
11The Icicle Kit development platform is based on PolarFire SoC and capable
12of running Linux.

Padmarao Begari0a04ad62021-01-15 08:20:41 +053017The support for following drivers are already enabled:
18
191. NS16550 UART Driver.
202. Microchip Clock Driver.
213. Cadence MACB ethernet driver for networking support.
224. Cadence MMC Driver for eMMC/SD support.

44The current U-Boot port is supported in S-mode only and loaded from DRAM.
45
46A prior stage M-mode firmware/bootloader (e.g HSS with OpenSBI) is required to
47boot the u-boot.bin in S-mode.
48
49Currently, the u-boot.bin is used as a payload of the HSS firmware (Microchip
50boot-flow) and OpenSBI generic platform fw_payload.bin (with u-boot.bin embedded)
51as HSS payload (Custom boot-flow)

Padmarao Begari0a04ad62021-01-15 08:20:41 +0530440Program eMMC with payload binary and Linux image is explained in the
441PolarFire SoC documentation.
442The payload binary should be copied to partition 2 of the eMMC.
443
444(Note: PolarFire SoC Documentation git repo is at https://github.com/polarfire-soc/polarfire-soc-documentation/blob/master/boards/mpfs-icicle-kit-es/updating-icicle-kit/updating-icicle-kit-design-and-linux.md#eMMC)
445
446Once the Linux image and payload binary is copied to the eMMC, press CTRL+C
447in the HSS command line interface, then type 'boot' and enter to boot the newly
448copied payload and Linux image.

Padmarao Begari0a04ad62021-01-15 08:20:41 +0530462The HSS always picks up the HSS payload from a GPT partition with
463GIUD type "21686148-6449-6E6F-744E-656564454649" or sector '0' of the eMMC if no
