mb/ocp/monolake: add TPM and IPMI support
Changes includes: - enable TPM1 + add entry in devicetree - configure LPC IO to make IPMI work + add entry in devicetree - introduce DSDT and SMBIOS entries for IPMI to make it detectable by ipmi_si driver Signed-off-by: Lukasz Siudut <lsiudut@fb.com> Change-Id: Ia975643064075f1f861f4ead6f24ed71f345ea04 Reviewed-on: https://review.coreboot.org/c/coreboot/+/32443 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Rudolph <siro@das-labor.org> Reviewed-by: Philipp Deppenwiese <zaolin.daisuki@gmail.com>
