Microchip PolarFire SoC Icicle Kit
==================================
RISC-V PolarFire SoC
--------------------
2021-01-25 19:11:54 +00:00
2021-01-15 02:50:41 +00:00
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
----------------
2021-01-25 19:11:54 +00:00
2021-01-15 02:50:41 +00:00
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

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

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)

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.

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:

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.

Program eMMC with payload binary and Linux image is explained in the
PolarFire SoC documentation.
The payload binary should be copied to partition 2 of the eMMC.
(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 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.

sudo dd if=<payload_binary> of=/dev/sdX2 bs=512
You should see the U-Boot prompt on UART0.

The HSS always picks up the HSS payload from a GPT partition with
GIUD type "21686148-6449-6E6F-744E-656564454649" or sector '0' of the eMMC if no
GPT partition.
