commit 54572eaeed24c5f257ac4209a99e148b4e3ffd39 Author: Alexandru Gagniuc mr.nuke.me@gmail.com Date: Sat Aug 29 18:53:43 2015 -0700
UNTESTED: drivers/intel/fsp1_1: Take platform ID as a string, not integers
The platform ID is an 8 character ASCII string, so our config should take it in as a string, rather than a set of two 32-bit integers.
