Rick Chen 31fbf6032d Use dts support from U-Boot via OF_SEPARATE instead of depending from opensbi. 
This would help to make the necessary changes in drivers and device trees
in U-Boot tree itself. This feature would also be helpful to not pass
dtb during opensbi builds.

HiFive Unleashed
================
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.
4. SiFive SPI Driver.
5. MMC SPI Driver for MMC/SD support.
TODO:
1. 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@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) 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:
.. code-block:: none
make PLATFORM=sifive/fu540 FW_PAYLOAD_PATH=<path to u-boot-dtb.bin>
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.
.. 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.
