Texas Instrument's System Control Interface (TI-SCI) Message Protocol is used in Texas Instrument's System on Chip (SoC) such as those in keystone family K2G SoC to communicate between various compute processors with a central system controller entity. TI-SCI message protocol provides support for management of various hardware entities within the SoC. Add support driver to allow communication with system controller entity within the SoC using the mailbox client. We introduce the basic registration and query capability for the driver protocol as part of this change. Subsequent patches add in functionality specific to the TI-SCI features.

|
|
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.

BIOS tries boot from. This information is then exported via sysfs.

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.)
