SandyBridge/IvyBridge: Use flash map to find MRC cache
Until now, the MRC cache position and size was hard coded in Kconfig. However, on ChromeOS devices, it should be determined by reading the FMAP. This patch provides a minimalistic FMAP parser (libflashmap was too complex and OS centered) to allow reading the in-ROM flash map and look for sections. This will also be needed on some partner devices where coreboot will have to find the VPD in order to set up the device's mac address correctly. The MRC cache implementation demonstrates how to use the FMAP parser.
