From 3ef0e1f8cad0a851b3dbf91802b14af7dd780352 Mon Sep 17 00:00:00 2001 From: Andres Salomon Date: Tue, 29 Apr 2008 00:59:53 -0700 Subject: x86: olpc: add One Laptop Per Child architecture support This adds support for OLPC XO hardware. Open Firmware on XOs don't contain the VSA, so it is necessary to emulate the PCI BARs in the kernel. This also adds functionality for running EC commands, and a CONFIG_OLPC. A number of OLPC drivers depend upon CONFIG_OLPC. olpc_ec_timeout is a hack to work around Embedded Controller bugs.
