2021-02-15sfi: Remove framework for deprecated firmwareAndy Shevchenko1-93/+0
SFI-based platforms are gone. So does this framework. This removes mention of SFI through the drivers and other code as well.

2013-12-07SFI / ACPI: Fix warnings reported during builds with W=1Lv Zheng1-0/+3
The following warnings can be seen in W=1 builds, because the original sfi_acpi.[ch] header inclusions are incorrect: include/linux/sfi_acpi.h:72:2: error: implicit declaration of function 'acpi_table_parse' [-Werror=implicit-function-declaration] drivers/sfi/sfi_acpi.c:154:5: warning: no previous prototype for 'sfi_acpi_table_parse' [-Wmissing-prototypes] Fix linux/sfi_acpi.h and modify drivers/sfi/sfi_acpi.c accordingly.

2013-12-07ACPI: Clean up inclusions of ACPI header filesLv Zheng1-1/+1
Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h> inclusions and remove some inclusions of those files that aren't necessary. First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h> should not be included directly from any files that are built for CONFIG_ACPI unset, because that generally leads to build warnings about undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set, <linux/acpi.h> includes those files and for CONFIG_ACPI unset it provides stub ACPI symbols to be used in that case. Second, there are ordering dependencies between those files that always have to be met. Namely, it is required that <acpi/acpi_bus.h> be included prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the latter depends on are always there. And <acpi/acpi.h> which provides basic ACPICA type declarations should always be included prior to any other ACPI headers in CONFIG_ACPI builds. That also is taken care of including <linux/acpi.h> as appropriate.

2012-06-23ACPI: mark acpi_sfi_table_parse() as __initJiang Liu1-2/+2
Mark function acpi_sfi_table_parse() as __init to avoid warning messages: WARNING: vmlinux.o(.text+0x4cd2d2): Section mismatch in reference from the function acpi_sfi_table_parse.clone.0() to the function Function acpi_sfi_table_parse() calls acpi_table_parse() and pci_parse_mcfg(), which are both marked as __init. Currently acpi_sfi_table_parse() is only used by MMCONFIG to scan MCFG table at boot time only, so it's safe to mark acpi_sfi_table_parse() as __init.

2009-08-29SFI: add capability to parse ACPI tablesFeng Tang1-0/+93
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.
