+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_generic_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)

+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)
+
+Program eMMC with HSS Payload
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+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 with HSS Payload
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The HSS always picks up HSS payload from a GPT partition with
+GUID type "21686148-6449-6E6F-744E-656564454649" or sector '0' of the eMMC if no
+GPT partition.
+
+Booting with HSS Payload
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+You should see the U-Boot prompt on UART1.
+(Note: UART0 is reserved for HSS)

-Currently, the u-boot.bin is used as a payload of the HSS firmware (Microchip

-eMMC
-~~~~
-
-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.

-You should see the U-Boot prompt on UART1.

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