SUMMARY = "Generates download.bit using updatemem"
DESCRIPTION = "download.bit is a bitstream with an elf binary in it. \
This recipe will take a bitstream without any elf binary in it and add \
an elf file to it. By default fs-boot.elf is embedded into the bitstream, \
this can be overriding by setting DATA_FILE in your build environment"
