[LinuxBIOS] [PATCH] BCOM Winnet100 support

Juergen Beisert juergen127 at kreuzholzen.de
Tue Oct 9 19:51:48 CEST 2007


Hi,

this patch adds main support for BCOM's Winnet100 Geode GX1 based terminal.
It activates the VGA support so it would be possible to run this target as a
small (and silent) X terminal. With faster SDRAM timing (not yet supported in
mainline) it can run graphical resolutions up to SXGA (1280x1024) at 64k
colours.

I'm not sure if all files I add to src/mainboard/bcom/winnet100 are required.
Most of them are copies from other GX1 based mainboards.

Tested on my IGEL316 terminal (=BCOM Winnet100) with 64MiB SDRAM,
kernel 2.6.22 and Xorg 7.1.

Subject: Adding BCOM Winnet100

From: Juergen Beisert <juergen at kreuzholzen.de>

This patch adds BCOM's winnet100 to the supported mainboards.
Refer http://www.linuxbios.org/index.php/BCOM_WINNET100_Build_Tutorial
for hardware description.

Patch is against LinuxBIOSv2, revision of 2007-10-09
