Author: stefanct Date: Wed Aug 20 17:39:32 2014 New Revision: 1844 URL: http://flashrom.org/trac/flashrom/changeset/1844
Log: Add support for Intel Silvermont: Bay Trail, Rangeley and Avoton.
The core of this patch to support Bay Trail originally came from the Chromiumos flashrom repo and was modified by Sage to support the Rangeley/Avoton parts as well. Because that was not complicated enough already Stefan Tauner refactored and refined everything. Bay Trail seems to be the first Atom SoC able to support hwseq. No SPI Programming Guide could be obtained so it is handled similarly to Lynx Point which seems to be its nearest relative.
