[PATCH v4 0/7] Microchip PolarFire SoC support
This patch set adds Microchip PolarFire SoC Icicle Kit support to RISC-V U-Boot.
The patches are based upon latest U-Boot tree (https://gitlab.denx.de/u-boot/u-boot.git) at commit id 7889951d0f56eab746a7c8fde350a022ba0361ca
All drivers namely: NS16550 Serial, Microchip clock, Cadence eMMC and Cadence MACB Ethernet work fine on actual Microchip PolarFire SoC Icicle Kit.
Changes in v4: - Add dual-license GPL or MIT in the device tree - Replace microsemi compatible strings with microchip - Add MACB compatible string for Microchip PolarFire SoC ethernet - Update MACB driver for 32-bit/64-bit DMA based on compatible string
Changes in v3: - Add 'default y if 64BIT' for config DMA_ADDR_T_64BIT - Update MACB driver for 32-bit/64-bit DMA based on design config register - Add phy-handle in MACB driver to read the phy address from device tree - Fix checkpatch warnings in the clock driver - Remove fu540 related compatible strings from soc device tree node - Move refclk device tree node under /soc device tree node - Use local-mac-address instead of mac-address in the device tree - Rename device tree to microchip-mpfs-icicle-kit.dts - Add U-Boot specific dts microchip-mpfs-icicle-kit-u-boot.dtsi file - Drop the imply DMA_ADDR_T_64BIT from board config - Fix some typos - Update doc with Microchip and Custom boot-flow
Changes in v2: - Add clock frequency for the clint device tree node - Move peripheral device tree nodes under /soc device tree node - Device tree nodes are in order based on the address - Enable UART0 for U-Boot logs - Update doc for the U-Boot logs are on UART0 - Move clock and reset index source into patch4 - Remove "dma_addr_r" type in the macb driver - Add lower_32_bits() for 32-bit address in the macb driver - Add set_rate() returns the new clock rate in the clock driver

Is there a reason why this etherent port is disabled?
Yes, the Icicle kit has two ethernet ports but only one MDIO interface between MAC and PHY-dual port is available i.e connected with ethernet 1 and other port(ethernet 0) MDIO interface is not connected with PHY in the FPGA design that's why it is disabled. only one ethernet port is enabled in the fpga design for Linux bring-up on the Icicle kit at present.
We will update our FPGA design in the future to enable both ethernet ports.

This patch adds Microchip MPFS Icicle Kit support. For now, only NS16550 Serial, Microchip clock, Cadence eMMC and MACB drivers are only enabled. The Microchip MPFS Icicle defconfig by default builds U-Boot for S-Mode because U-Boot on Microchip PolarFire SoC will run in S-Mode as payload of HSS + OpenSBI.

+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:

+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.

+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

This patch set adds Microchip PolarFire SoC Icicle Kit support to RISC-V U-Boot.
The patches are based upon latest U-Boot tree (https://gitlab.denx.de/u-boot/u-boot.git) at commit id 7889951d0f56eab746a7c8fde350a022ba0361ca
All drivers namely: NS16550 Serial, Microchip clock, Cadence eMMC and Cadence MACB Ethernet work fine on actual Microchip PolarFire SoC Icicle Kit.
Changes in v4:
- Add dual-license GPL or MIT in the device tree
- Replace microsemi compatible strings with microchip
- Add MACB compatible string for Microchip PolarFire SoC ethernet
- Update MACB driver for 32-bit/64-bit DMA based on compatible string
Changes in v3:
- Add 'default y if 64BIT' for config DMA_ADDR_T_64BIT
- Update MACB driver for 32-bit/64-bit DMA based on design config register
- Add phy-handle in MACB driver to read the phy address from device tree
- Fix checkpatch warnings in the clock driver
- Remove fu540 related compatible strings from soc device tree node
- Move refclk device tree node under /soc device tree node
- Use local-mac-address instead of mac-address in the device tree
- Rename device tree to microchip-mpfs-icicle-kit.dts
- Add U-Boot specific dts microchip-mpfs-icicle-kit-u-boot.dtsi file
- Drop the imply DMA_ADDR_T_64BIT from board config
- Fix some typos
- Update doc with Microchip and Custom boot-flow
Changes in v2:
- Add clock frequency for the clint device tree node
- Move peripheral device tree nodes under /soc device tree node
- Device tree nodes are in order based on the address
- Enable UART0 for U-Boot logs
- Update doc for the U-Boot logs are on UART0
- Move clock and reset index source into patch4
- Remove "dma_addr_r" type in the macb driver
- Add lower_32_bits() for 32-bit address in the macb driver
- Add set_rate() returns the new clock rate in the clock driver

Can you please rename the files clk_pfsoc_* to mpfs_clk_*? I know this naming is inconsistent but we need to start somewhere. Also pfsoc-clock.h to mpfs-clock.h.
