Randy reported build errors in linux-next where XIP_KERNEL was enabled.
ARCH_THEAD requires alternatives to support the non-standard ISA
extensions used by the THEAD cores, which are mutually exclusive with
XIP kernels. Clone the dependency list from the Allwinner entry, since
Allwinner's D1 uses T-Head cores with the same non-standard extensions.

This enables support for the RISC-V based T-HEAD SoCs.

I need to take it, I applied the patches.
Sorry, probably should have said it below the --- line.

I don't have an ARCH_THEAD, though, so not sure where this is aimed at.

No problem, I figured they were over there somewhere -- just kind of
hard to keep track with how much is in flight right now ;)

Applied to riscv-dt-for-next, thanks!
[1/1] RISC-V: make ARCH_THEAD preclude XIP_KERNEL
