Bin Meng 85546a5477 treewide: Use conventional names for 32-bit and 64-bit 
There are several places in the source tree that have:

  32bit, 32 bit, 64bit, 64 bit

Fix by using the conventional names with a hyphen.

QEMU SiFive Unleashed Machine Platform

The QEMU SiFive Unleashed Machine is an emulation of the SiFive Unleashed platform.

To build this platform specific library and firmwares, provide the PLATFORM=qemu/sifive_u parameter to the top level make command line.

Platform Options

The QEMU SiFive Unleashed Machine platform does not have any platform specific options.

Executing on QEMU RISC-V 64-bit

No Payload Case

Build:

make PLATFORM=qemu/sifive_u

Run:

qemu-system-riscv64 -M sifive_u -m 256M -display none -serial stdio \
	-kernel build/platform/qemu/sifive_u/firmware/fw_payload.elf

U-Boot as a Payload

Note: the command line examples here assume that U-Boot was compiled using the sifive_fu540_defconfig configuration.

Build:

make PLATFORM=qemu/sifive_u FW_PAYLOAD_PATH=<uboot_build_directory>/u-boot.bin

Run:

qemu-system-riscv64 -M sifive_u -m 256M -display none -serial stdio \
	-kernel build/platform/qemu/sifive_u/firmware/fw_payload.elf

or

qemu-system-riscv64 -M sifive_u -m 256M -display none -serial stdio \
	-kernel build/platform/qemu/sifive_u/firmware/fw_jump.elf \
	-device loader,file=<uboot_build_directory>/u-boot.bin,addr=0x80200000
