Subject: [PATCH] powerpc/boot: regenerate zImage linker script when options change
Date: Sat, 26 Nov 2016 15:00:00 +1100 [thread overview]
Message-ID: <20161126040000.25052-1-npiggin@gmail.com> (raw)
Changing config options (e.g., endianness) does not always seem to
regenerate zImage.lds properly. Adapt the standard kernel linker script
build command and use that.
