Adds helpers to do SMC and HVC based on ARM SMC Calling Convention. CONFIG_HAVE_ARM_SMCCC is enabled for architectures that may support the SMC or HVC instruction. It's the responsibility of the caller to know if the SMC instruction is supported by the platform. This patch doesn't provide an implementation of the declared functions. Later patches will bring in implementations and set CONFIG_HAVE_ARM_SMCCC for ARM and ARM64 respectively.

help
|
|
System Control and Power Interface (SCPI) Message Protocol is
|
|
defined for the purpose of communication between the Application
|
|
Cores(AP) and the System Control Processor(SCP). The MHU peripheral
|
|
provides a mechanism for inter-processor communication between SCP
|
|
and AP.
|
|
|
|
SCP controls most of the power managament on the Application
|
|
Processors. It offers control and management of: the core/cluster
|
|
power states, various power domain DVFS including the core/cluster,
|
|
certain system clocks configuration, thermal sensors and many
|
|
others.
|
|
|
|
This protocol library provides interface for all the client drivers
|
|
making use of the features offered by the SCP.

help
|

Say Y or M here if you want to enable BIOS Enhanced Disk Drive
|
|
Services real mode BIOS calls to determine which disk
|
|
BIOS tries boot from. This information is then exported via sysfs.
|
|
|
|
This option is experimental and is known to fail to boot on some
|
|
obscure configurations. Most disk controller BIOS vendors do
|
|
not yet implement this feature.

Say Y if you want EDD disabled by default, even though it is compiled into the

Add the firmware-provided (unmodified) memory map to /sys/firmware/memmap.
|
|
That memory map is used for example by kexec to set up parameter area
|
|
for the next kernel, but can also be used for debugging purposes.

|
|
help
|
|
If your firmware supplies the PCDP table, and you want to
|
|
automatically use the primary console device it describes
|
|
as the Linux console, say Y here.
|
|
|
|
If your firmware supplies the HCDP table, and you want to
|
|
use the first serial port it describes as the Linux console,
|
|
say Y here. If your EFI ConOut path contains only a UART
|
|
device, it will become the console automatically. Otherwise,
|
|
you must specify the "console=hcdp" kernel boot argument.
|
|
|
|
Neither the PCDP nor the HCDP affects naming of serial devices,
|
|
so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending
|
|
on how the driver discovers devices.
|
|
|
|
You must also enable the appropriate drivers (serial, VGA, etc.)
