commit 1a82de2b58c285fed98ced2af76a61b02afba3ed Author: Kyösti Mälkki kyosti.malkki@gmail.com Date: Thu Feb 9 16:07:41 2012 +0200
AMD Geode cpus: apply un-written naming rules
Kconfig directives to select chip drivers for compile literally match the chip directory names capitalized and underscored.
Rename directories and Kconfig as follows: model_lx -> geode_lx model_gx1 -> geode_gx1 model_gx2 -> geode_gx2
