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.
This series is also available here [1] for testing
[1] https://github.com/pragnesh26992/u-boot/tree/spl
How to test this patch:
1) Go to OpenSBI-dir : make PLATFORM=generic FW_DYNAMIC=y
2) export OPENSBI=<path to opensbi/build/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)
