From a56b99879680890283a4f0a9788b950d48b41986 Mon Sep 17 00:00:00 2001 From: Luc Verhaegen Date: Sun, 20 May 2007 16:16:13 +0000 Subject: Flashrom: add support for ASUS P5A (Socket 7, ALi based). * Add support for the ALi M1533 to chipset_enable.c * Add some SMBus poking needed for the ASUS P5A, to board_enable.c Since PCI subsystem IDs are worthless with this board, people will have to name the board directly.
