commit 5bfdb8779d1eda9700156db0b265a64a47a48d37 Author: Ronald G. Minnich rminnich@gmail.com Date: Wed Feb 20 15:46:46 2013 -0800
google/snow: enable GPIO entries and CHROMEOS in building
These were not separable or it would have been two CLs.
Enable CHROMEOS configure option on snow. Write gpio support code for the mainboard. Right now the GPIO just returns hard-wired values for "virtual" GPIOs.
This is tested and creates gpio table entries that our hardware can use.
Lots still missing but we can now start to fill in the blanks, since we have enabled CHROMEOS for this board. We are getting further into the process of actually booting a real kernel.
