# Generate rimage modules from the base kernel ELF file. Note the
# warning squashing on the objcopy steps. Binutils has a misfeature
# where if the copy removes all the sections from an input ELF program
# header (our link generates lots of phdrs because of the disjoint
# cacheability addresses), it will warn about an "empty" segment even
# though it was TOLD to drop the contents!
#
# Also note that rimage is picky with section flags: it will try to
# include a section in the output data (even its own metadata in
# .module!) if it has any of ALLOC, WRITABLE or EXEC flags in the ELF
# file. The GNU linker will set these automatically based on the
# flags of the sections coming out of C code, so this is fragile and
# breaks easily. Set noload flags explicitly here.

# If some of your board(s) need to override default rimage parameters
# then you can define WEST_SIGN_OPTS in boards/my/board/board.cmake.
# Example:
#
# set(WEST_SIGN_OPTS -- -c "/home/sweet home/rimage/config/abc.toml" -i 4)
# Parameters after the double dash -- are passed through to rimage. For
# other ways to override default rimage parameters check
# boards/xtensa/intel_adsp_cavs25/doc/intel_adsp_generic.rst
# Warning: because `west sign` can also be used interactively, using
# ${WEST_SIGN_OPTS} like this has _higher_ precedence than `west config
# rimage.extra-args`! Avoid overriding default rimage parameters in
# multiple places to avoid unexpected precedence rules.
