Author: uwe Date: 2008-11-18 23:32:05 +0100 (Tue, 18 Nov 2008) New Revision: 1044
Modified: coreboot-v3/device/pnp_device.c coreboot-v3/include/device/pnp.h coreboot-v3/superio/fintek/f71805f/superio.c coreboot-v3/superio/ite/it8712f/superio.c coreboot-v3/superio/ite/it8716f/superio.c coreboot-v3/superio/winbond/w83627hf/superio.c coreboot-v3/superio/winbond/w83627thg/superio.c Log: This is the first part of a v3 Super I/O refactoring.
Add a small collection of PNP enter/exit functions for many Super I/Os. Use these functions instead of duplicating them for each chip.
