Atish Patra 8ad2104589 doc: Add a readme guide for SiFive FU540 
The readme guide describes the procedure to build, flash and boot Linux
using U-Boot on HiFive Unleashed. It also explains the current state of
U-boot support and future action items.

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@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.
