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 depends on: [1] https://patchwork.ozlabs.org/patch/1281853 [2] https://patchwork.ozlabs.org/patch/1281852
All these together is available for testing here [3] [3] https://github.com/pragnesh26992/u-boot/tree/spl
How to test this patch:
- Go to OpenSBI-dir : make PLATFORM=generic FW_DYNAMIC=y
- export
OPENSBI=<path/to/opensbi/build/platform/generic/firmware/fw_dynamic.
bi n> 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)

Changes in v11:
- Remove TPL related code and OF_PLATDATA from FU540 DDR driver (drivers/ram/sifive/fu540_ddr.c)
- Update FU540 doc (doc/board/sifive/fu540.rst) Remove unnecessary print
Could we get this v11 applied as soon as possible for v2020.07?
No problem, if everything is OK, I will applied ASAP. But Jagan seem have some responses, please check about it.

With " assigned-clocks" and " assigned-clock-rates" for cpus, this FU540 SPL series is no more depend on the above patches.
cpus { assigned-clocks = <&prci PRCI_CLK_COREPLL>; assigned-clock-rates = <1000000000>; ..... }
I will update the series dependency in v12. Thanks to @Sean Anderson for the suggestion.
Looks this series "riscv: Add Sipeed Maix support" was not applied neither ?
Yes, the reason is that the CI verification of v10 of this series "riscv: Add Sipeed Maix support" still fail. Please check the discussion of [v10,20/21] doc: riscv: Add documentation for Sipeed Maix Bit

That is why I still not pull it yet.
Thanks, Rick
