Hi Yunhui,

From that discussion it was mentioned that that arm supports 3 methods
of booting:
direct + devicetree
EFI + devicetree
EFI + ACPI
..but not
direct + ACPI

To me it isn't obvious from that or this thread, and since arm seems
to be doing fine without the 4th option I'm curious why that's
necessary on riscv?

Also you didn't answer this question, which I'd also like to hear a reply to.
