Subject: microblaze: fix race condition in building boot images
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=52e79c4f0bfd972d7176a26d58d163cc18bf6d6a;p=linux.git

microblaze: fix race condition in building boot images

I fixed a race condition in the parallel building of ARM in commit
3939f3345050 ("ARM: 8418/1: add boot image dependencies to not
generate invalid images").

I see the same problem for MicroBlaze too.

"make -j<N> ARCH=microblaze all linux.bin.ub" results in a broken build
because two threads descend into arch/microblaze/boot simultaneously.

Add proper dependencies to avoid it.
