Author: hailfinger

New Revision: 1032

Modified:
   coreboot-v3/superio/winbond/w83627thg/stage1.c
   coreboot-v3/superio/winbond/w83627thg/superio.c
Log:
Drop duplicated functions from W83627THG SuperI/O stage1 code and fix
up a function prototype.

Fix up #include statements for W83627THG SuperI/O stage2 code.
Use anonymous instead of named unions in struct device.
Point pnp_dev_info members to w83627thg_ops.     
Disable UART and keyboard initialization for now.
Add new code in phase3_chip_setup_dev to fill in configuration values
from the dts (code is partially disabled).
