This series add support for SPL to FU540.U-Boot SPL can boot from
L2 LIM (0x0800_0000) and jump to OpenSBI(FW_DYNAMIC firmware) and
U-Boot proper from MMC devices.

How to test this patch:
1) Go to OpenSBI-dir : make PLATFORM=generic FW_DYNAMIC=y
2) export OPENSBI=<path/to/opensbi/install_dir/platform/generic/firmware/fw_dynamic.bin>
3) Change to u-boot-dir
4) make sifive_fu540_defconfig
5) make all
6) Format the SD card (make sure the disk has GPT, otherwise use gdisk to switch)

	# sudo sgdisk --clear \
	> --set-alignment=2 \
	> --new=1:34:2081 --change-name=1:loader1 --typecode=1:5B193300-FC78-40CD-8002-E86C45580B47 \
	> --new=2:2082:10273 --change-name=2:loader2 --typecode=2:2E54B353-1271-4842-806F-E436D6AF6985 \
	> --new=3:10274: --change-name=3:rootfs --typecode=3:0FC63DAF-8483-4772-8E79-3D69D8477DE4 \
	> /dev/sda

7) sudo dd if=spl/u-boot-spl.bin of=/dev/sda seek=34
8) sudo dd if=u-boot.itb of=/dev/sda seek=2082
