commit 688f18b304a53e97b83076602a67476e10e1add4 Author: Kyösti Mälkki kyosti.malkki@gmail.com Date: Thu Jun 28 21:41:05 2012 +0300
Enable ROM cache for payload decompression on all boards
The static size of 8 MB ChromeOS defines for SPI flash would extend over write-protection control MMIO of older LPC/FWH flash, so use a configurable region size instead.
