It needs more than a little work :-) I have lots of changes that
attempt to support sleep mode on the Au1xxxx. Everything from
saving/restoring core state, to sdram self refresh, to driver
modifications for PM functions. I've done this in the sourceforge
kernel and will update the linux-mips tree as I have time. Some
of the patches will likely require some debate, as they touch software
outside of the core Au1xxx functions.
In addition to the kernel modifications, you need a boot rom that
will support the kernel. It has to detect a wakeup condition, bring
the memory back the life, perform some processor initialization, and
then return to the kernel. Basically, copy what Yamon does. ;-)
If someone is seriously working on this, drop me a note and we can
