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 fix has been in linux-next since Monday. Noticed your PRs hadn't gone out, so figured I should send this, rather than let the issue sneak into mainline. --- arch/riscv/Kconfig.socs | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/riscv/Kconfig.socs b/arch/riscv/Kconfig.socs index ce10a38dff37..6833d01e2e70 100644 --- a/arch/riscv/Kconfig.socs +++ b/arch/riscv/Kconfig.socs @@ -43,6 +43,7 @@ config ARCH_SUNXI config ARCH_THEAD bool "T-HEAD RISC-V SoCs" + depends on MMU && !XIP_KERNEL select ERRATA_THEAD help This enables support for the RISC-V based T-HEAD SoCs.
