This series add support for SPL to FU540. This series depends on https://patchwork.ozlabs.org/patch/1196703/ (riscv: dts: Add hifive-unleashed-a00 dts from Linux)
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=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_spl_defconfig 5) make all 6) SD card partition which contains "fw_payload.bin" previously /dev/sdc1 - SiFive bare-metal (or s ->5202) should be now of /dev/sdc1 - 8300 Linux filesystem. 6) sudo dd if=spl/u-boot-spl.bin of=/dev/sdc4 bs=1M 7) sudo dd if=u-boot.itb of=/dev/sdc1 bs=1M
Following are the boot messages on FU540 five cores SMP platform:
