We get a harmless warning if the ARM_SCPI_POWER_DOMAIN driver is enabled
without CONFIG_OF during compile testing:
warning: (ARM_SCPI_POWER_DOMAIN) selects PM_GENERIC_DOMAINS_OF which has unmet direct dependencies (PM_GENERIC_DOMAINS && OF)
There is no need to select PM_GENERIC_DOMAINS_OF if OF is set, so we can
replace the 'select' with a dependency.

|
|
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

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.)
