Allwinner currently offers d1(s)/v821/v861/v881 on RISC-V,
using different IPs.

d1(s): Xuantie C906
v821: Andes A27 + XuanTie E907
v861/v881: XuanTie C907

Han Gao (3):
  riscv: soc: re-organized allwinner menu
  riscv: soc: allwinner: d1: use the ARCH_SUNXI_XUANTIE
  riscv: defconfig: enable SUNXI_XUANTIE and SUNXI_ANDES

This series is incomplete. It introduces ARCH_SUNXI_ANDES symbol but it is
never used.

Additionally, patches are not organized properly. First, you should introduce
reorganization and only then introduce new features. Also, not a single
patch should break existing functionality for bisectability reasons. First
patch breaks compilation of DT files while second restores that. This must
not happen.

Best regards,
Jernej
