Subject: kbuild: remove scripts/multiconfig.sh
X-Git-Tag: v2015.04-rc5~49
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=5f9eb2207500f16a598866884f8ee5343ae8949f;p=u-boot

kbuild: remove scripts/multiconfig.sh

We have switched to the single .config configuration system,
the same one as used in Linux Kernel.

The necessary glue code is small enough now, so move it to the
top-level Makefile and scripts/kconfig/Makefile, and then delete
scripts/multiconfig.sh.
