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
cp install_dir/platform/sifive/fu540/firmware/fw_dynamic.bin <u-boot-dir>/
Change to u-boot-dir
make sifive_fu540_defconfig
make all
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
