Author: libv Date: 2009-11-28 19:07:51 +0100 (Sat, 28 Nov 2009) New Revision: 786
Modified: trunk/board_enable.c Log: Boards: provide enormous intel_ich_gpio_set function. This code sets gpio lines on random intel ichs. Detects all currently known intel ICHs, checks gpio lines, and then sets them accordingly.
