-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. SPI driver is still missing. So MMC card can't be used in U-Boot as of now.
-2. U-Boot expects the serial console device entry to be present under /chosen
- DT node. Example:
- chosen {
- stdout-path = "/soc/serial at 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 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.
-
-The description of steps required to build the firmware is beyond the scope of
-this document. Please refer OpenSBI or BBL 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.
-
-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.

+================
+
+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. SPI driver is still missing. So MMC card can't be used in U-Boot as of now.
+2. U-Boot expects the serial console device entry to be present under /chosen
+ DT node. Without a serial console U-Boot will panic. Example:
+
+.. code-block:: none
+
+ chosen {
+ stdout-path = "/soc/serial at 10010000:115200";
+ };
+
+Building
+--------
+
+1. Add the RISC-V toolchain to your PATH.
+2. Setup ARCH & cross compilation enviornment variable:
+
+.. code-block:: none
+
+ export ARCH=riscv
+ 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 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.
+
+The description of steps required to build the firmware is beyond the scope of
+this document. Please refer OpenSBI or BBL 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.
+
+.. code-block:: none
+
+ 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.
