[PATCH 0/5] patches to settle i8042 with Intel MID platforms

[PATCH 0/5] patches to settle i8042 with Intel MID platforms

[feng.tang]

From: Feng Tang <feng.tang@intel.com>

Hi All,

Some x86 platforms like intel MID platforms don't have i8042 controllers,
and i8042 driver's probe to some non-exist legacy IO ports may hang
the MID processor. 

Current solution for this is add dependency of SERIO_I8042 over
!X86_MRST, then if we build a x86 kernel image with X86_MRST=y,
it won't have i8042 driver support over common x86 platforms.

So we add a i8042 pre-detect hook into x86_platforms ops, so that
i8042 driver can use it to run-time judge whether to go on with
probe process.

Please review these patches.

Thanks,
Feng

[PATCH 1/5] x86: add i8042 pre-detection hook to x86_platform_ops

[feng.tang]

From: Feng Tang <feng.tang@intel.com>

Some x86 platforms like intel MID platforms don't have i8042 controllers,
and i8042 driver's probe to some legacy IO ports may hang the MID
processor. With this hook, i8042 driver can runtime check and skip the
probe when the pretection fail which also saves some probe time

I think this needs to be protected with "#ifdef CONFIG_X86" as the file is 
shared between X86 and IA64.

That's going to break IA64 :(

I have to say there is an awful lot of code in that file which is
specific to x86 (more so than IA64)... anyone has a feel if it would
make sense to break it up?

Almost all of the X86 specific lines are actually just data definitions
for dmi_system_id structures that list systems that need special handling.
Many (most) of the recent changes to this file are adding new systems to
these structures.

We could push them all out into a separate file (as shown in the patch
below) ... then the remainining CONFIG_X86 lines in i8042-x86ia64io.h
look a lot less imposing.  But I'm not sure whether this really gains
anything.

I don't think a naive split of the file into x86 and ia64 versions would
be a good idea ... apart from those massive structures there are a fairly
small number of arch specific lines (7 __ia64__ lines and 18 CONFIG_X86
lines out of 353 total lines).
