[PATCH] [MIPS] Remove unused header file gio.h

[PATCH] [MIPS] Remove unused header file gio.h

[Dmitri Vorobiev]

Grepping reveals that arch/mips/include/asm/sgi/gio.h is
not used by anyone, so let's delete the orphan header.

NAK, I have work in progress, which adds GIO devices and uses this
file.

That's interesting news! May I ask you which ones you're working on?

first step is to introduce GIO devices similair to PCI devices. My
current working GIO device is solid impact. I also looked at
supporting Phobos G160 cards, but the current set of 2114x drivers
is not useable for that...

The big missing thing in the GIO framework right now is a bullet proof
detection for non standard GIO cards, like newport and XZ cards. They
don't provide ID information...

So the resulting code will be a mix of normal probing bus code and
something like "GIO platform devices" which are just added if we somehow
"know" they're there?  SGI never stops to amaze me ...

Newport and XZ are probeable somehow, PROM and IRIX gfxinit are able
to do that. I want to integrate the documented probing and the special
probes into the GIO framework.

FWIW, I also have one of the ThunderLAN GIO cards for IP22, if you want to cook 
up a driver for that to test this for networking devices.  I also have a G130 
too, both plugged into my Indy.
