PS2, Line 9: Control Mini v1/v2 automatic power on by adding a 'board_settings' file
           : to CBFS.  This allows us to use one build each for Mini v1/v2 that is
           : configured differently for different uses.  By default, the EC setting is
           : not configured by coreboot, and the OS could configure it.
           : 
           : Add ITE SuperIO configuration to device tree and configure base address
           : of BRAM1.  (BRAM1 contains the EC firmware setting for automatic power
           : on.)
           : 
           : Test: Build Mini v2, boot with no settings in CBFS.  Add board_settings
           : configured for automatic power-on, flash, boot, confirm EC now powers
           : on automatically when power applied.

I only found the general `Documentation/lib/option.md`. Otherwise, `cmos.layout` and `cmos.default` in the source code tree.
