-FU540-C000 RISC-V SoC
-=====================
-The FU540-C000 is the world’s first 4+1 64-bit RISC‑V SoC from SiFive.
-
-The HiFive Unleashed development platform is based on FU540-C000 and capable
-of running Linux.
-
-Mainline support
-================
-The support for following drivers are already enabled:
-1. SiFive UART Driver.
-2. SiFive PRCI Driver for clock.
-3. Cadence MACB ethernet driver for networking support.
-
-TODO:
-1. U-Boot expects the serial console device entry to be present under /chosen
- DT node. Example:
- chosen {
- stdout-path = "/soc/serial@10010000:115200";
- };
-
- Without a serial console U-Boot will panic.
-
-Building
-========
-1. Add the RISC-V toolchain to your PATH.
-2. Setup ARCH & cross compilation enviornment variable.
- a. export ARCH=riscv
- b. export CROSS_COMPILE=<riscv64 toolchain prefix>
-3. make sifive_fu540_defconfig
-4. make
-
-Flashing
-========
-The current U-Boot port is supported in S-mode only and loaded directly
-into DRAM.
-
-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.
-
-Currently, the u-boot.bin is used as a payload of the OpenSBI FW_PAYLOAD
-firmware. We need to compile OpenSBI with below command:
-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)
-
-Once the prior stage firmware/bootloader binary is generated, it should be
-copied to the first partition of the sdcard.
-
-sudo dd if=<prior_stage_firmware_binary> of=/dev/disk2s1 bs=1024
-
-Booting
-=======
-Once you plugin the sdcard and power up, you should see the U-Boot prompt.
