Rather than have the EDD depend on !ia64 (and assuming that only ia64, x86, x86_64 will be including this Kconfig), have EDD depend on the only arches which can support this code. This should allow all other arches to cleanly include the firmware Kconfig. Also simplify the x86 string used by FIRMWARE_MEMMAP to match EDD.

tristate "BIOS Enhanced Disk Drive calls determine boot disk"

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
|
|
kernel. Say N if you want EDD enabled by default. EDD can be dynamically set
|
|
using the kernel parameter 'edd={on|skipmbr|off}'.

help
|
|
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.

default n

help
|

If you say Y here, you are able to get EFI (Extensible Firmware
|
|
Interface) variable information via sysfs. You may read,
|
|
write, create, and destroy EFI variables through this interface.
|
|
|
|
Note that using this driver in concert with efibootmgr requires
|
|
at least test release version 0.5.0-test3 or later, which is
|
|
available from Matt Domsch's website located at:
|
|
<http://linux.dell.com/efibootmgr/testing/efibootmgr-0.5.0-test3.tar.gz>

config EFI_PCDP

bool "Console device selection via EFI PCDP or HCDP table"

depends on ACPI && EFI && IA64

default y if IA64
|
|
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.)
