Subject: AMD Geode cpus: apply un-written naming rules
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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
