soc/intel: Allow enable/disable ME via CMOS
Add .enable method that will set the CSME state. The state is based on the new CMOS option me_state, with values of 0 and 1. The method is very stable when switching between different firmware platforms. This method should not be used in combination with USE_ME_CLEANER. State 1 will result in: ME: Current Working State : 4 ME: Current Operation State : 1 ME: Current Operation Mode : 3 ME: Error Code : 2 State 0 will result in: ME: Current Working State : 5 ME: Current Operation State : 1 ME: Current Operation Mode : 0 ME: Error Code : 0 Tested on: KBL-R: i7-8550u CML: i3-10110u, i7-10710u TGL: i3-1110G4, i7-1165G7 Signed-off-by: Sean Rhodes <sean@starlabs.systems> Change-Id: I374db3b7c0ded71cdc18f27970252fec7220cc20 Reviewed-on: https://review.coreboot.org/c/coreboot/+/52800 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Tim Crawford <tcrawford@system76.com> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org>
