Author: stuge Date: Thu Jan 27 12:43:03 2011 New Revision: 6304 URL: https://tracker.coreboot.org/trac/coreboot/changeset/6304
Log: Add new ec subdir for Embedded Controllers and common ACPI EC support Adds a new src/ec subdir for embedded controllers (mostly found in laptops) and converts Getac P470 and Roda RK886EX to use the new ACPI EC instead of having their own copies of those functions.
