siemens/mc_apl1: Extend circuit life by clock gating and power gating
The firmware of devices connected to LPC should deassert the LPC CLKRUN# signal when there is no bus activity on LPC. Necessary changes: - Enable LPC CLKRUN# - Enable LPC PCE (Power Control Enable) - Enable LPC CCE (Clock Control Enable) - Remove I/O decoding range on LPC for COM 3 - Disable I/O UART driver Change-Id: I2fd80e3fdcf23658f97b8182a77df7e09ddf25d6 Signed-off-by: Mario Scheithauer <mario.scheithauer@siemens.com> Reviewed-on: https://review.coreboot.org/28268 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Werner Zeh <werner.zeh@siemens.com> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net>
