smp_send_timer() prototype to asm/smp.h

From a63ae4427c6af66d6eda26e5da8fed53f8fbede3 Mon Sep 17 00:00:00 2001

Subject: [ARM] 3093/1: SharpSL PCMCIA Updates for Cxx00 models

Patch from Richard Purdie

The Sharp SL-Cxx00 models have a combined power control for the SD
and CF slot 0. This patch adds hooks to the scoop driver to allow
machines to provide a custom control function for this and such a
function is added for spitz/akita/borzoi.

It also moves the gpio init code into the machine files as this
is machine dependent and differs between some models. A couple of
warnings when compiling for collie are also fixed.

From 5285eb57c9a20d8df2569c770ff6048c3202cc91 Mon Sep 17 00:00:00 2001
From: Nicolas Pitre <nico@cam.org>
Date: Tue, 8 Nov 2005 22:43:06 +0000
Subject: [ARM] 3135/1: harden SA11x0 and PXA2xx timer init code

Patch from Nicolas Pitre

Make it completely deterministic and leave nothing to chance
(even if it had at worst 0.001% probability of failing).
