# This makefile allows you generate a program which will program an SPI flash
# part with another program.
# It requires that the PROGRAMMINGFILE variable to set to a binary copy of a
# program to program the SPI flash with. The file must already exist, the script
# will not automagically compile it for you.
# eg.
# $ make spiflash-program.elf PROGRAMMINGFILE=../gpio/gpio-board.bin
# This binary file is then converted to a version that will be loaded into the
# SPI flash (the size of the image is set in the first word), and then converted
# to an object file with the data in a section called .spiprogram
# A linker script is then used to put this section into the resulting ELF file
# that will do the programming of the SPI flash
# Simply running this program on the processor should program the SPI flash
# memory.
