configs

• buildroot default configs are now stored in buildroot/configs/apfxx_defconfig and no more in buildroot/target/device/armadeus/apfxx/apfxx_defconfig
• uClibc config should be named with version number to not overwrite the old one -->

buildroot/target/device/armadeus/apf27/uClibc-0.9.30.config.arm

• idem for U-Boot config:

buildroot/target/device/armadeus/apf27/apf27-u-boot-2010.03.h

How to use new BR in armadeus

• checkout a clean GIT view
• select the version to use with an envt variable:

$ export BUILDROOT_VERSION=2010.11

• then you can use it as old BR:

$ make apf27_defconfig
$ make

• new patches dir:

patches/buildroot/2010.11/
