 回覆: [PATCH v10 00/14] riscv: Add support for xtheadvector

The devicetree name shown in OpenSBI is
the one packed with U-Boot SPL.
As the image builder didn't put the kernel
devicetree with the image under boot partition,
The whole boot process only uses the U-Boot device tree.

The reason why the log shows "Nezha"
but not "Lichee RV" is that this log is produced
which U-Boot revision is d1-2022-10-31 from samuel's repo.
Build from d1-wip can show "Lichee RV" correctly
(manually edit config to specify LicheeRV dtb should have same effect though),
while the issue persists when kernel load to
the procedure same as the dmesg mentioned above.


Cheers,
Aoba K
