TODO:
The current U-Boot port is supported in S-mode only and loaded from DRAM.
-A prior stage (M-mode) firmware/bootloader (e.g OpenSBI or BBL) is required to
-load the u-boot.bin into memory and provide runtime services. The u-boot.bin
-can be given as a payload to the prior stage (M-mode) firmware/bootloader.
+A prior stage M-mode firmware/bootloader (e.g OpenSBI) is required to
+boot the u-boot.bin in S-mode and provide M-mode runtime services.
-The description of steps required to build the firmware is beyond the scope of
-this document. Please refer OpenSBI or BBL documenation.
+Currently, the u-boot.bin is used as a payload of the OpenSBI FW_PAYLOAD
+firmware. We need to compile OpenSBI with below command:
+
+.. code-block:: none
+
+ make PLATFORM=sifive/fu540 FW_PAYLOAD_PATH=<path to u-boot.bin> FW_PAYLOAD_FDT_PATH=<path to hifive-unleashed-a00.dtb from Linux>
+
+(Note: Prefer hifive-unleashed-a00.dtb from Linux-5.3 or higher)
+(Note: Linux-5.2 is also fine but it does not have ethernet DT node)
+
+More detailed description of steps required to build FW_PAYLOAD firmware
+is beyond the scope of this document. Please refer OpenSBI documenation.
(Note: OpenSBI git repo is at https://github.com/riscv/opensbi.git)
-(Note: BBL git repo is at https://github.com/riscv/riscv-pk.git)
Once the prior stage firmware/bootloader binary is generated, it should be
copied to the first partition of the sdcard.
