[PATCH v3 0/4] mkimage: sunxi_egon: add riscv support

[Samuel Holland]

This patchset updates 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 v3 is a minor update to Icenowy's patch series, which I have
also tested. Since the TOC0 patch series touches the same lines in
Makefile.spl, it depends on this series.

Changes in v3:
- Factor out an egon_get_arch() function as suggested by Andre

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
