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:
- Go to OpenSBI-dir : make PLATFORM=generic FW_DYNAMIC=y
- 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)

Changes in v12:
Rebase on mainline U-Boot Added necessary include files which are not part of common header now Remove unnecessary include files

Update commit description for Release ethernet clock reset
Update OpenSBI building section in "doc/board/sifive/fu540.rst"
Thanks. During the testing I found there is one issue about ethernet.
The 1000Mbps does not work. Only 100Mbps works. Could you please have a look?
Yes, you are right. This is because ethernet clock rate is not setting properly.
FSBL set the ethernet clock rate to 125 Mhz. https://github.com/sifive/freedom-u540-c000-bootloader/blob/master/fsbl/main...
U-Boot can do the same with below lines:
eth0: ethernet@10090000 { +assigned-clocks = <&prci PRCI_CLK_GEMGXLPLL>; +assigned-clock-rates = <125000000>; };
I will update this in v13, thanks for the testing.
Please share your latest version, I will update the partition table.
Which partition table are you going to update?
SD according to SPI.
Jagan.
