Commit 85611e3febe78955a519f5f9eb47b941525c8c76 ("x86, intel-mid:
Add Clovertrail platform support") added new instances of __cpuinit
usage. We removed this a couple versions ago; we now want to remove
the compat no-op stubs. Introducing new users is not what we want to
see at this point in time, as it will break once the stubs are gone.

This is a cleanup proposed by coccinelle. It replaces memcpy with struct
assignment on intel-mid's sfi layer.

This patch does cleanup on all intel mid platform code that uses
gpio_get_by_name() function. From now on they should check for any error
code instead of only hardcoded -1.
There are no functional changes from this change.

When Intel MID finds a match between SFI table from FW and registered
SFI devices, it will always register a device regardless the platform
code was successful or not.
This patch adds an extra option for platform code to return error code
and abort device registration on SFI table parsing.
This patch does not contain any functional changes for current intel
mid platform code.

In order make the driver more portable and support other Intel MID
(Mobile Internet Device) platforms we need to move Medfield code from
intel-mid.c core to its own mfld.c file.
This patch contains no functional changes.

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

As Intel rolling out more SoC's after Moorestown, we need to
re-structure the code in a way that is backward compatible and easy to
expand. This patch implements a flexible way to support multiple boards
and devices.
This patch does not add any new functional support. It just refactors
the existing code to increase the modularity and decrease the code
duplication for supporting multiple soc's and boards.
Currently intel-mid.c has both board and soc related code in one file.
This patch moves the board related code to new files and let linker
script to create SFI devite table following this:
1. Move the SFI device specific code to
arch/x86/platform/intel-mid/device-libs/platform_<device>.*
A new device file is added for every supported device. This code will
get conditionally compiled by using corresponding device driver
CONFIG option.
2. Move the device_ids location to .x86_intel_mid_dev.init section by
using new sfi_device() macro.
This patch was based on previous code from Sathyanarayanan Kuppuswamy.

Moved SFI specific parsing/handling code to sfi.c. This will enable us
to reuse our intel-mid code for platforms that supports firmware

This patch provides a means to add custom handler for
SFI devices. If you set device_handler as NULL in
device_id table standard SFI device handler will be used.
If its not NULL custom handler will be called.

SFI device_id[] table parsing code is duplicated in every SFI
device handler. This patch removes this code duplication, by
adding a seperate function get_device_id() to parse through the
device table. Also this patch moves the SPI, I2C, IPC info code from
sfi_parse_devs() to respective device handlers.

mrst is used as common name to represent all intel_mid type
soc's. But moorsetwon is just one of the intel_mid soc. So
renamed them to use intel_mid.
This patch mainly renames the variables and related
functions that uses *mrst* prefix with *intel_mid*.
To ensure that there are no functional changes, I have compared
the objdump of related files before and after rename and found
the only difference is symbol and name changes.

Following files contains code that is common to all intel mid
soc's. So renamed them as below.
mrst/mrst.c -> intel-mid/intel-mid.c
mrst/vrtc.c -> intel-mid/intel_mid_vrtc.c
mrst/early_printk_mrst.c -> intel-mid/intel_mid_vrtc.c
pci/mrst.c -> pci/intel_mid_pci.c
Also, renamed the corresponding header files and made changes
to the driver files that included these header files.
To ensure that there are no functional changes, I have compared
the objdump of renamed files before and after rename and found
that the only difference is file name change.
