[PATCH v2 04/18] ARM: zynq: move header generation to zynq_mkimage

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Instead of generating a suitable image header with linker magic, move
all of this into zynq_mkimage. The configuration file format and parsing
is based on imx-image. This gets us one step further on the road to
proper multi-image support.
