Hi,
It appears that as of QEMU 9.1, it's possible to boot LoongArch machines
that don't provide EFI or ACPI.
Would you consider removing the `select ACPI` and `select EFI` from the
arch Kconfig, so that kernels built for this minimal QEMU environment
can be a bit leaner and quicker to build?
Jason

Add huacai who is maintainer of Loongarch Linux kernel.

Very difficult, at least removing EFI is difficult. Even if booting to
a FDT environment, we still get information from EFI now.

Makes sense. !ACPI is the more interesting one for me, anyway, as that
takes a while to build.
