+Microchip PolarFire SoC Icicle Kit
+==================================
+
+RISC-V PolarFire SoC
+--------------------
+The PolarFire SoC is the 4+1 64-bit RISC-V SoC from Microchip.
+
+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.
+
+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=<riscv64 toolchain prefix>
+
+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. Configure
+
+.. code-block:: none
+
+ make BOARD=icicle-kit-es config
+
+Alternatively, copy the default config for Microchip boot-flow.
+
+.. code-block:: none
+
+ cp boards/icicle-kit-es/def_config .config
+
+2. make BOARD=icicle-kit-es
+3. In the Default subdirectory, the standard build will create hss.elf and
+ various binary formats (hss.hex and hss.bin).
+
+The FPGA design will use the hss.hex or hss.bin.
+
+FPGA design with HSS programming file
+-------------------------------------
+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
+
+The HSS firmware runs from the PolarFire SoC eNVM on reset.
+
+Creating the HSS payload - Microchip boot-flow
+----------------------------------------------
+1. You will be creating a payload from `u-boot-dtb.bin`.
+ Copy this file to the HSS/tools/hss-payload-generator/test directory.
+2. Go to hss-payload-generator source directory.
+
+.. code-block:: none
+
+ cd hart-software-services/tools/hss-payload-generator
+
+3. Edit test/uboot.yaml file for hart entry points and correct name of the binary file.
+
+ hart-entry-points: {u54_1: '0x80200000', u54_2: '0x80200000', u54_3: '0x80200000', u54_4: '0x80200000'}
+
+ payloads:
+ test/u-boot-dtb.bin: {exec-addr: '0x80200000', owner-hart: u54_1, secondary-hart: u54_2, secondary-hart: u54_3, secondary-hart: u54_4, priv-mode: prv_s}
+
+4. Generate payload
+
+.. code-block:: none
+
+ ./hss-payload-generator -c test/uboot.yaml payload.bin
+
+Once the payload binary is generated, it should be copied to the eMMC.
+
+Please refer to HSS documenation to build the HSS firmware for payload.
+(Note: HSS git repo is at https://github.com/polarfire-soc/hart-software-services/blob/master/tools/hss-payload-generator/README.md)
+
+Custom boot-flow
+----------------
+HSS without OpenSBI (M-Mode) -> OpenSBI (M-Mode) -> U-Boot (S-Mode) -> Linux (S-Mode)
+
+Build OpenSBI
+-------------
+
+1. Get the OpenSBI source
+
+.. code-block:: none
+
+ git clone https://github.com/riscv/opensbi.git
+ cd opensbi
+
+2. Build
+
+.. code-block:: none
+
+ make PLATFORM=generic FW_PAYLOAD_PATH=<u-boot-directory>/u-boot.bin
+ FW_FDT_PATH=<u-boot-directory>/arch/riscv/dts/microchip-mpfs-icicle-kit-.dtb
+
+3. Output "fw_payload.bin" file available at
+ "<opensbi-directory>/build/platform/generic/firmware/fw_payload.bin"
+
+Build the HSS (Hart Software Services)- Custom boot-flow
+--------------------------------------------------------
+(Note: HSS git repo is at https://github.com/polarfire-soc/hart-software-services)
+
+1. Configure
+
+.. code-block:: none
+
+ make BOARD=icicle-kit-es config
+
+Alternatively, copy the default custom config for Custom boot-flow.
+
+.. code-block:: none
+
+ cp boards/icicle-kit-es/def_config_custom .config
+
+2. make BOARD=icicle-kit-es
+3. In the Default subdirectory, the standard build will create hss.elf and
+ various binary formats (hss.hex and hss.bin).
+
+The FPGA design will use the hss.hex or hss.bin.
+
+Creating the HSS payload - Custom boot-flow
+-------------------------------------------
+1. You will be creating a payload from `fw_payload.bin`.
+ Copy this file to the HSS/tools/hss-payload-generator/test directory.
+2. Go to hss-payload-generator source directory.
+
+.. code-block:: none
+
+ cd hart-software-services/tools/hss-payload-generator
+
+3. Edit test/uboot.yaml file for hart entry points and correct name of the binary file.
+
+ hart-entry-points: {u54_1: '0x80000000', u54_2: '0x80000000', u54_3: '0x80000000', u54_4: '0x80000000'}
+
+ payloads:
+ test/fw_payload.bin: {exec-addr: '0x80000000', owner-hart: u54_1, secondary-hart: u54_2, secondary-hart: u54_3, secondary-hart: u54_4, priv-mode: prv_m}
+
+4. Generate payload
+
+.. code-block:: none
+
+ ./hss-payload-generator -c test/uboot.yaml payload.bin
+
+Once the payload binary is generated, it should be copied to the eMMC.
+
+Please refer to HSS documenation to build the HSS firmware for payload.
+(Note: HSS git repo is at https://github.com/polarfire-soc/hart-software-services/blob/master/tools/hss-payload-generator/README.md
+and also refer the HSS payload generator at https://github.com/polarfire-soc/polarfire-soc-documentation/blob/master/software-development/hss-payloads.md)
+
+eMMC
+----
+Program eMMC with payload binary is explained in the PolarFire SoC documentation.
+(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)
+
+Once the payload image is copied to the eMMC, press CTRL+C in the HSS command
+line interface, then type 'boot' and enter to boot the newly copied image.
+
+.. code-block:: none
+
+ sudo dd if=<payload_binary> of=/dev/sdX bs=512
+
+GUID type
+---------
+The HSS always picks up HSS payload from a GPT partition with
+GIUD type "21686148-6449-6E6F-744E-656564454649" or sector '0' of the eMMC if no
+GPT partition.
+
+Booting
+-------
+You should see the U-Boot prompt on UART0.
