at91: fix image building with CONFIG_TARGET_MULTI_PROFILE
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. Fixes: d7a679a036 ("at91: Install zImage.") Signed-off-by: Jo-Philipp Wich <jo@mein.io>
