[RFC PATCH 0/4] mkimage: sunxi_egon: add riscv support

[Icenowy Zheng]

This patchset tries to make mkimage -T sunxi_egon to be able to generate
an eGON.BT0 image for Allwinner RISC-V SoCs (e.g. D1).

In addition, to keep the compatibility, it will still consider the
architecture to be ARM when no architecture is specified.

This patchset is RFC because I have no idea whether the change to
mkimage common code is proper (maybe we should just change default value
to IH_ARCH_INVALID?).

Icenowy Zheng (4):
  mkimage: add a flag to describe whether -A is specified
  mkimage: sunxi_egon: refactor for multi-architecture support
  mkimage: sunxi_egon: add support for riscv
  sunxi: specify architecture when generating SPL boot image
