+This documents what I did to change from
+ buildroot version 2012.05 to 2014.08
+
+- update README and bin/build-release
+ README: change 'br_ver'
+ bin/build-release: BR_VER="2012.05"
+- update patches to make sure they apply
+ ( cd buildroot && QUILT_PATCHES=$PWD/../patches-buildroot quilt push -a )
+ remove obsolete patches from series and delete .patch files.
+- update default config for all arches
+ there has to be a better way to do this, but for now:
+ arches=$(for f in conf/buildr*.config; do a=${f##*-}; echo ${a%.*}; done)
+ for arch in $arches; do
+ make br-config ARCH=$arch
+ done
+- update path to uclibc config referenced in buildroot-*.conf
+ f=".*/uClibc-.*.config"; t="package/uclibc/uClibc-0.9.33.config"
+ sed -i -e "s,$f,$t" conf/buildroot-*.config
+- update path to busybox config
+ Hopefully this was only a one time thing, as i took out the version
+ in the path.
+ # manually changed to package/busybox/busybox-cirros.config
+ vi conf/buildroot-*.config
+
+ Also changed Makefile to address this
+- update Makefile for change in location of 'skeleton' in buildroot tree
+ Hopefully one time
+- update path to device_table.txt
+ Hopefully one time.
+ f="target/generic/device_table.txt"; t="system/device_table.txt"
+ sed -i -e "s,$f,$t,p" conf/buildroot-*.config
+
+- update Makefile for determining busybox version
+ Hopefully one time
+ now this works: make ARCH=i386 br-busybox-menuconfig
+
+- update busybox config
+ make ARCH=i386 br-busybox-menuconfig
+ save
