d943f2c821 arm/plat-mxc: Fix forgotten renaming in timer.c
Commit "mxc: Change gpt timer code to be more generic by using V2
instead of MX3" forgot to replace one occurence causing a build
failure.

38a66f51e7 mxc: Change gpt timer code to be more generic by using V2 instead of MX3
Replace mx3_ with v2_ since the register layout is the same for all SoCs using
version 2 of the timer (mx25, mx31, mx37 and now mx51)

0f3332c4fa mxc: refactor timer code to use timer versions
Refactor the timer code into version 1 and version 2.

Essentially there are 2 versions of the timer hardware on Freescale MXC
hardware. Version 1 is found on MX1/MXL, MX21 and MX27. Version 2 is found on
MX25, MX31, MX35, MX37, MX51, and future parts.

ec996ba9b5 mxc timer: make compile time independent
Currently we depend on hardcoded base addresses for the timer.
This prevents us from compiling in more than one i.MX architecture
at a time. This patch changes the base address to a runtime
calculated one.

058b7a6f46 arm/imx2x: removes a bunch of sparse-warnings
Here are some of the warnings that get fixed by this:

> 200 times: warning: cast adds address space to expression (<asn:2>)
twelve times: warning: symbol 'xxx' was not declared. Should it be static
two times: warning: symbol 'clock' shadows an earlier one
five times: warning: incorrect type in initializer (different address spaces)

30c730f8f9 [ARM] MXC: rework timer/clock initialisation
- rename mxc_clocks_init to architecture specific versions. This
  allows us to have more than one architecture compiled in.
- call mxc_timer_init from clock initialisation instead from board
  code

320ab2b0b1 cpumask: convert struct clock_event_device to cpumask pointers.
Impact: change calling convention of existing clock_event APIs

struct clock_event_timer's cpumask field gets changed to take pointer,
as does the ->broadcast function.

Another single-patch change.  For safety, we BUG_ON() in
clockevents_register_device() if it's not set.

Remove includes of asm/hardware.h in addition to asm/arch/hardware.h.
Then, since asm/hardware.h only exists to include asm/arch/hardware.h,
update everything to directly include asm/arch/hardware.h and remove
asm/hardware.h.

d0f349fbce i.MXC family: Adding timer support
This patch adds timer support for the i.MX machine family. This code can
be used on the following machs:

 - i.MX1 (tested)
 - i.MX2 (i.MX21 (to be tested), i.MX27 (tested))
 - i.MX3 (i.MX31 (tested))

TODO: It seems impossible to build a kernel for more than one CPU because the
timer do not follow the platform device rules. So it does only work if
timer 1 can be accessed on all CPUs at the same address.
