mb/intel/mtlrvp: Enable GSPI interface
This patch enables GSPI [1] interface for mtlrvp based on mtlrvp schematics. BUG=b:224325352 BRANCH=None TEST=Able to observe corresponding UPD configuration with FSP dump and able to boot mtlrvp (LP5/DDR5) to ChromeOS. (Base patch for CB:71223) SPI[0].Mode = 0 SPI[0].DefaultCsOutput = 0 SPI[0].CsMode = 0 SPI[0].CsState = 0 SPI[1].Mode = 1 SPI[1].DefaultCsOutput = 0 SPI[1].CsMode = 0 SPI[1].CsState = 0 Signed-off-by: Harsha B R <harsha.b.r@intel.com> Change-Id: I3d4c4f19dd80fefa80c365b5ecac0a234f5af860 Signed-off-by: Jamie Ryu <jamie.m.ryu@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/72706 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Eric Lai <eric_lai@quanta.corp-partner.google.com> Reviewed-by: Sridhar Siricilla <sridhar.siricilla@intel.com>
