Yes.  This is same case.  The concern is that FSP uses 42 and coreboot reports 42 to OS in DMAR table while coreboot still use 46 in some of module.  So, the concern is coreboot is using both 46 and 42 as physical address width if CONFIG_SOC_PHYSICAL_ADDRESS_WIDTH is defined as 42 while cpu register reports 46.
