+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/boa... +/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)

You could also add a reference to this document which is geared more towards using the HSS payload generator and includes links to pre-built images: https://github.com/polarfire-soc/polarfire-soc-documentation/blob/master/sof...

+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/boa... +/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.

+Sample boot log from MPFS Icicle Kit +-------------------------------------------

+.. code-block:: none

+once the Linux image and payload binary is copied to the eMMC, press CTRL+C +in the HSS command line interface, then type 'boot' and enter to boot the newly +copied payload and Linux image.

Uppercase "O" for once?
