The current image build code has a number of race conditions and interface
contract violations in the custom image build steps:
- Build/install-zImage, solely used by at91, relies on $(PROFILE_SANITIZED)
which is not available when building with CONFIG_TARGET_MULTI_PROFILE
- Build/at91-sdcard, which may run concurrently, creates scratch files at
fixed locations and manipulates target files directly which can lead
to file corruption and other unexpected failures
Rename the install-zImage macro to at91-install-zImage and move it to the
at91 image Makefile since this target is the sole user. Also utilize "$@"
as output file name and switch the usage of $(PROFILE_SANITIZED) to
$(DEVICE_NAME) in order to fix naming under multi profile builds.
Fix the at91-sdcard macro to construct scratch file paths relative to "$@",
which is guaranteed to be unique and store the final artifact output in "$@"
as well, instead of inside $(BIN_DIR). The generic image build code takes
care of moving a build steps "$@" output to the final destination in a
concurrency-safe manner.
Finally remove the broken install-zImage from the generic image-commands
Makefile.
