This adds support for resetting via assertion of GPIO pin.
This e.g. is used on Sharp Zaurus SL-6000.

This patch adds basic mach support for the mx2 processor family, based
on the original freescale code and adapted to mainline kernel coding
style.
This part adds the global build only.

The Phytec phyCORE-i.MX27 CPU module is delivered with the PCM970
baseboard by default. This patch adds support for the hardware.
This code is only an empty stub; it is filled up with functionality
in a later patch series.

This patch adds support for the phyCORE-i.MX27 cpu module (aka pcm038).
It is as generic as possible in order to support any kind of baseboard.
Note: This CPU module implementation can't work without a baseboard
support. Baseboard support can be added by the PCM-970 (included in
this patch stack) or any custom variant.

Internal clock path handling for the i.MX27 CPU.
Changed against the original Freescale code (and against clocklib for example):
- clock rate is always calculated whenever one ask for the current rate.
(means no "rate" member in the clock structure).
So switching the PLL base frequency will propagate immediately to all
other clocks that are depending on this frequency.
TODO:
- Check if the i.MX21 CPU can share the same code.

This patch adds basic support for i.MX31 LiteKit by LogicPD.
With printascii() in kernel/printk.c, it boots right into the
rootfs-panic.
Note: This is a modified version of Daniel's patch to fit into this patch
stack.

Currently there is a mx31ads BSP file in the kernel, but no default
config file.
This patch adds a basic default config for the imx31ads but it is for test
purposes only to ensure the i.MX2 patch stack doesn't break the i.MX3.
Note: For reference only. This configuration is untested as I have
no access to an mx31ads.

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.

This patch bases on the one from Daniel Mack. The most important change to
Daniel's patch is to be more generic. This gpio routine supports at least
the i.MX27 and i.MX31 processors.

Internal clock path handling for the mxc CPUs.
Changed against the original Freescale code (and against clocklib for example):
- clock rate is always calculated whenever one ask for the current rate

base frequency will propagate immediately to all other clocks that are

The S3C2410 serial driver in drivers/serial/s3c2410.c has been
growing bigger with the addition of more variants of this hardware
with the growing Samsung SoCs range. As such, it would be
easier to split this code up into a core and per-cpu drivers to
make driver addition easier, and the core smaller.

to use pata_platform and thus libata to provide IDE support.

Use the pata_platform driver to provide the IDE port
drivers on the Simntec BAST and Thorcom VR1000 machines
as a precursor to removing drivers/ide/arm/bast-ide.c
This will mean that the system will need SCSI and SCSI disc
support as a minimum, and any references to hdX will be
changed to sdX.
