Not all machines have PCI style I/O port memory, or they do not allow
mapping it using the ioport_map() function, whcih results in a
build error with the newly added qemu firmware code:
drivers/firmware/built-in.o: In function `fw_cfg_io_cleanup':
qemu_fw_cfg.c:(.text+0x144): undefined reference to `ioport_unmap'
drivers/firmware/built-in.o: In function `fw_cfg_sysfs_probe':
qemu_fw_cfg.c:(.text+0xb18): undefined reference to `ioport_map'
This adds a Kconfig dependency to ensure the driver can only
be built on platforms that support it.

|
|
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.

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.

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.)
