13 depends on ARM_MHU
14 help
15 System Control and Power Interface (SCPI) Message Protocol is
16 defined for the purpose of communication between the Application
17 Cores(AP) and the System Control Processor(SCP). The MHU peripheral
18 provides a mechanism for inter-processor communication between SCP
19 and AP.
20
21 SCP controls most of the power managament on the Application
22 Processors. It offers control and management of: the core/cluster
23 power states, various power domain DVFS including the core/cluster,
24 certain system clocks configuration, thermal sensors and many
25 others.
26
27 This protocol library provides interface for all the client drivers
28 making use of the features offered by the SCP.

34 Say Y or M here if you want to enable BIOS Enhanced Disk Drive
35 Services real mode BIOS calls to determine which disk
36 BIOS tries boot from. This information is then exported via sysfs.
37
38 This option is experimental and is known to fail to boot on some
39 obscure configurations. Most disk controller BIOS vendors do
40 not yet implement this feature.

56 That memory map is used for example by kexec to set up parameter area
57 for the next kernel, but can also be used for debugging purposes.

65 help
66 If your firmware supplies the PCDP table, and you want to
67 automatically use the primary console device it describes
68 as the Linux console, say Y here.
69
70 If your firmware supplies the HCDP table, and you want to
71 use the first serial port it describes as the Linux console,
72 say Y here. If your EFI ConOut path contains only a UART
73 device, it will become the console automatically. Otherwise,
74 you must specify the "console=hcdp" kernel boot argument.
75
76 Neither the PCDP nor the HCDP affects naming of serial devices,
77 so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending
78 on how the driver discovers devices.
79
80 You must also enable the appropriate drivers (serial, VGA, etc.)
