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
