From 447240808c62cb877e343c40802a35d01ed198fb Mon Sep 17 00:00:00 2001 From: Timothy Pearson Date: Mon, 16 Mar 2015 11:47:45 -0500 Subject: lib: Add Kconfig option to enable/disable auto fallback control Under certain conditions, e.g. automated testing, it is useful to have the payload (e.g. Linux) reset the reboot_bits CMOS value. This allows automated recovery in the case of coreboot starting properly but the payload failing to start due to bad configuration data provided by the coreboot image under test.
