This very small patch adds support for little endian on the virtual QEMU mips platform. The status of this platform is the same as the big endian one, ie it is possible to boot a system with init=/bin/sh.

Qemu is a software emulator which among other architectures also
|
|
can simulate a MIPS32 4Kc system. This patch adds support for the
|
|
system architecture that currently is being simulated by Qemu. It
|
|
will eventually be removed again when Qemu has the capability to
|
|
simulate actual MIPS hardware platforms. More information on Qemu
|

can be found at http://www.linux-mips.org/wiki/Qemu.

Please make sure to pick the right CPU type. Linux/MIPS is not

designed to be generic, i.e. Kernels compiled for R3000 CPUs will

*not* work on R4000 machines and vice versa. However, since most

of the supported machines have an R4000 (or similar) CPU, R4x00

might be a safe bet. If the resulting kernel does not work,

try to recompile with R3000.

APM is a BIOS specification for saving power using several different

techniques. This is mostly useful for battery powered systems with
|
|
APM compliant BIOSes. If you say Y here, the system time will be

|
reset after a RESUME operation, the /proc/apm device will provide

|
battery status information, and user-space programs will receive
|
|
notification of APM "events" (e.g. battery status change).
|
|
|
|
In order to use APM, you will need supporting software. For location
|
|
and more information, read <file:Documentation/pm.txt> and the
|
|
Battery Powered Linux mini-HOWTO, available from

manpage ("man 8 hdparm") for that), and it doesn't turn off

VESA-compliant "green" monitors.

|
|
|
Generally, if you don't have a battery in your machine, there isn't
|
|
much point in using this driver and you should say N. If you get
|
|
random kernel OOPSes or reboots that don't seem to be related to
|

anything, try disabling/enabling this option (or disabling/enabling
