[ Upstream commit 0cfccb3c04934cdef42ae26042139f16e805b5f7 ]
The top-level boot_targets (uImage and uImage.*) should be phony targets. They just let Kbuild descend into arch/arc/boot/ and create files there.
If a file exists in the top directory with the same name, the boot image will not be created.
You can confirm it by the following steps:
$ export CROSS_COMPILE=<your-arc-compiler-prefix> $ make -s ARCH=arc defconfig all # vmlinux will be built $ touch uImage.gz $ make ARCH=arc uImage.gz CALL scripts/atomic/check-atomics.sh CALL scripts/checksyscalls.sh CHK include/generated/compile.h # arch/arc/boot/uImage.gz is not created
Specify the targets as PHONY to fix this.
