[PATCH v2 0/4] mkimage: sunxi_egon: add riscv support

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.

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
