Author: libv Date: 2009-12-23 01:54:26 +0100 (Wed, 23 Dec 2009) New Revision: 815
Modified: trunk/board_enable.c trunk/chipset_enable.c trunk/print.c Log: Chipset/Board: vt8237: Set All mem cycles to LPC in chipset enable. Only done for VT8237R (possibly needed for VT8237 too), VT8235 does not need this (even if the original bios does so: Asus A7V8X-MX SE, MSI KT4V were verified). This then opens a floodgate of cleanups in the board enables. * EPIA SP board enable vanishes, taking EPIA CN match with it. * Asus A7V8X-MX/Tyan S2498 board enable then equals w836xx_memw_enable_2e * AOpen vKM400Am-S board enable then equals it8705_rom_write_enable * Epia M board enable becomes via_vt823x_gpio15_raise * Epia N board enable becomes via_vt823x_gpio9_raise * Asus M2V-MX board enable becomes via_vt823x_gpio5_raise * vt823x_gpio_set becomes via_vt823x_gpio_set, and now detects ISA bridge itself, in concordance with intel ich and nvidia mcp gpio.
