SFI-based platforms are gone. So does this framework.
This removes mention of SFI through the drivers and other code as well.

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

The following commit:
5997efb96756 ("x86/boot: Use memremap() to map the MPF and MPC data")
causes new build failures on certain randconfigs:
drivers/sfi/sfi_core.c: In function ‘sfi_map_memory’:
drivers/sfi/sfi_core.c:104:10: error: implicit declaration of function ‘memremap’ [-Werror=implicit-function-declaration]
drivers/sfi/sfi_core.c:104:31: error: ‘MEMREMAP_WB’ undeclared (first use in this function)
This is a case of parasitic header dependencies: the sfi_core.c file indirectly
includes <linux/io.h> for typical - but not all configs.
Including <linux/io.h> explicitly solves the build failure.

The ioremap() function is intended for mapping MMIO. For RAM, the
memremap() function should be used. Convert calls from ioremap() to
memremap() when re-mapping RAM.
This will be used later by SME to control how the encryption mask is
applied to memory mappings, with certain memory locations being mapped
decrypted vs encrypted.

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.

There are 2 major changes from v0.81 to v0.7:
1. Consolidating the SPIB/I2CB tables into a new DEVS table,
which is more expandable and can support other bus types
than spi/i2c.
2. Creating a new GPIO table, which list all the GPIO pins
used in the platform.
However, to avoid breaking current platforms who use SFI v0.7
version firmware, the definitions for SPIB/I2CB will still
be kept for a while

sfi_verify_table() is called at runtime, and thus cannot be __init
Signed-off-by: Arjan van de Ven <[email protected]>

The function sfi_map_memory/sfi_unmap_memory uses
early_ioremap/early_iounmap respectively, which refers to a __init
function. And function sfi_check_table also refers to a __init function
sfi_verify_table. Since the references are valid, so use __ref to get rid
of the warnings.
We were warned by the following warnings:
LD vmlinux.o
MODPOST vmlinux.o
WARNING: vmlinux.o(.text+0xb6ba3a): Section mismatch in reference from
the function sfi_map_memory() to the function
.init.text:early_ioremap()
The function sfi_map_memory() references
the function __init early_ioremap().
This is often because sfi_map_memory lacks a __init
annotation or the annotation of early_ioremap is wrong.
WARNING: vmlinux.o(.text+0xb6bab6): Section mismatch in reference from
the function sfi_unmap_memory() to the function
.init.text:early_iounmap()
The function sfi_unmap_memory() references
the function __init early_iounmap().
This is often because sfi_unmap_memory lacks a __init
annotation or the annotation of early_iounmap is wrong.

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.

CONFIG_SFI=y enables the kernel to boot and run optimally
on platforms that support the Simple Firmware Interface.
Thanks to Jacob Pan for prototyping the initial Linux SFI support,
and to Feng Tang for Linux bring-up and debug both in emulation
and on Moorestown hardware.
