The <mach/gpio.h> file is included from upper directories
and deal with generic GPIO and gpiolib stuff. Break out the
platform and driver specific defines and functions into its own
header file.

The ep9307, ep9312, and ep9315 variants of the ep93xx processor include
the raster engine needed for framebuffer support.

This allows the EDB93xx boards with those processors to use the
framebuffer driver.

Tested on an EDB9307A with the following kernel parameters:
	video=640x480-16@60
	video=1024x768-16@60

Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.

The various declarations were removed using the following script:

  grep -rl MACHINE_START arch/arm | xargs \
  sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'

[ Initial patch was from Jeremy Kerr, example script from Russell King ]

Create a core.c __init function to handle the physmap flash
registration for all the ep93xx platforms.  Also, modify all
the ep93xx platforms to use this new function.

This simplifies all the ep93xx platform init code and reduces
the size of the kernel when including multiple ep93xx boards.

A number of the peripherals for the ep93xx are registered at
startup using platform_data that is passed from the board init
code to the core code.  This data is then copied to a local
static variable in the core code.  Since the data is copied,
the original data can be marked as __initdata and discarded
after startup is complete.

This adds the __initdata tag to all the appropriate data in
the various ep93xx board init's.  Specifically, all the
struct ep93xx_eth_data, struct ep93xxfb_mach_info, and
struct i2c_gpio_platform_data.

Also, document the various registration functions and note
what data should be marked as __initdata.

While here, also cleanup a couple over zealous whitespace tabs.

Update the ep93xx i2c support:

  1) The platform init code passes the configuration data for the
     i2c-gpio driver.  This allows any gpio pin do be used for the
     sda and scl pins.  It also allows the platform to specify the
     udelay and timeout.
  2) Program the gpio configuration register to enable/disable the
     open drain drivers.  Note that this really only works if the
     sda and scl pins are set to EP93XX_GPIO_LINE_EEDAT and
     EP93XX_GPIO_LINE_EECLK.
  3) Update the edb93xx.c platform init to use the new support.

arch/arm/mach-ep93xx/include/mach/hardware.h
  1. Properly name the include files so that they are loaded
     from the <mach/*> directory and not the local directory.
  2. Remove including the ts72xx.h header.  This header is not
     generic to the ep93xx platform.  It should only be included
     by the ts72xx specific files that require it.  The only
     two users in the tree are arch/arm/mach-ep93xx/ts72xx.c
     and drivers/mtd/nand/ts7250.c.

arch/arm/mach-ep93xx/include/mach/ts72xx.h
  1. <linux/io.h> should already be included by any user of this
     header.  Doing the include here hides it from being needed
     by the calling source file.

arch/arm/mach-ep93xx/core.c
  1. Remove unnecessary headers.  They were probably included
     originally due to cut-and-paste from other files.
  2. <linux/io.h> should be included not <mach/gpio.h>

arch/arm/mach-ep93xx/adsphere.c
arch/arm/mach-ep93xx/edb93xx.c
arch/arm/mach-ep93xx/gesbc9312.c
arch/arm/mach-ep93xx/micro9.c
arch/arm/mach-ep93xx/ts72xx.c
  1. Remove unnecessary headers.

arch/arm/mach-ep93xx/ts72xx.c
  1. Remove unnecessary headers.
  2. Add platform specific header <mach/ts72xx.h>.

drivers/mtd/nand/ts7250.c
  1. <linux/io.h> should be included not <asm/io.h>.
  2. Add platform specific header <mach/ts72xx.h>.

The Cirrus Logic EDB93xx development board platform init files
share redundant code. The only differences are in the flash
memory configuration, MACH_TYPE, and additional on-board
I2C devices. This patch merges all of them into one file.
