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)

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

Most patches improved from v6, but still few issues like - patches which are unrelated to MMC SPL support, please bypass and send them separately. - order of patches need to improve, take my suggestions and order them. - incorporate partition layout patches before SPL enablement patch.
