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:
- Go to OpenSBI-dir : make PLATFORM=sifive/fu540 O=build_dir
I=install_dir FW_DYNAMIC=y install 2) cp install_dir/platform/sifive/fu540/firmware/fw_dynamic.bin <u-boot-dir>/ 3) Change to u-boot-dir 4) make sifive_fu540_defconfig 5) make all 6) ZSBL loads the U-boot SPL(u-boot-spl.bin) from a partition with GUID type 5B193300-FC78-40CD-8002-E86C45580B47
sudo dd if=spl/u-boot-spl.bin of=/dev/sdc4 bs=1M
- U-boot SPL expects a u-boot FIT image(u-boot.itb) from 1st
partition(/dev/sdc1)
of SD card irrespective of GUID
sudo dd if=u-boot.itb of=/dev/sdc1 bs=1M
Seems like SPL (sdc4) at 4th partition and U-Boot proper at first partition which seems an unconventional way to create partition layouts based on the booting stage hierarchy.
I did send the changes on top of our changes [1] which indeed follow the conventional partition layout. So feel free to incorporate your series while sending the next version.
So from next version, you can drop CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_USE_PARTITION and write
images as,
$ sudo dd if=u-boot.itb of=/dev/sda seek=4096 $ sudo dd if=spl/u-boot- spl.bin of=/dev/sda seek=2048

Thanks Jagan, will update in v7.
I've reviewed the v6 patches. Since Jagan also sent several series related to SPI and booting from SPI that is dependent on this series, would you please post a v7 soon? We need get this SPL support merged as soon as possible. Thank you.
Will submit v7 soon.
