The Icicle Kit development platform is based on PolarFire SoC and capable of running Linux. Mainline support ---------------- The support for following drivers are already enabled: 1. NS16550 UART Driver. 2. Microchip Clock Driver. 3. Cadence MACB ethernet driver for networking support. 4. Cadence MMC Driver for eMMC/SD support. 5. Microchip I2C Driver. Booting from eMMC using HSS --------------------------- Building U-Boot ~~~~~~~~~~~~~~~ 1. Add the RISC-V toolchain to your PATH. 2. Setup ARCH & cross compilation environment variable: .. code-block:: none export CROSS_COMPILE= 3. make microchip_mpfs_icicle_defconfig 4. make Flashing ~~~~~~~~ The current U-Boot port is supported in S-mode only and loaded from DRAM. A prior stage M-mode firmware/bootloader (e.g HSS with OpenSBI) is required to boot the u-boot.bin in S-mode. Currently, the u-boot.bin is used as a payload of the HSS firmware (Microchip boot-flow) and OpenSBI generic platform fw_payload.bin (with u-boot.bin embedded) as HSS payload (Custom boot-flow) Microchip boot-flow ~~~~~~~~~~~~~~~~~~~ HSS with OpenSBI (M-Mode) -> U-Boot (S-Mode) -> Linux (S-Mode) Build the HSS (Hart Software Services) - Microchip boot-flow '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' (Note: HSS git repo is at https://github.com/polarfire-soc/hart-software-services) 1.
