the following patch was just integrated into master: commit e221aad27fb860f31be089180d920df9d2243ae2 Author: Bill Richardson wfrichar@chromium.org Date: Wed Jun 12 10:50:41 2013 -0700
ec: Reserve correct ioport regions for Chrome OS EC to use
The LPC-based ChromeOS EC uses several ioport regions to communicate with the AP. In order for the new unified userspace access method to work, we need them to be reserved by the BIOS.
Before /proc/ioports shows:
0800-0803 0804-08ff
We'd like just a single 256-byte region at 0x800, but ASL can't handle that. So this will work:
0800-087f 0880-08ff
