Extend SFI to access standard ACPI tables. (eg. the PCI MCFG) using sfi_acpi_table_parse(). Note that this is _not_ a hybrid ACPI + SFI mode. The platform boots in either ACPI mode or SFI mode. SFI runs only with acpi_disabled=1, which can be set at build-time via CONFIG_ACPI=n, or at boot time by the failure to find ACPI platform support. So this extension simply allows SFI-platforms to re-use existing standard table formats that happen to be defined to live in ACPI envelopes.
