Commit 2d66c78035 ("cpuimx27 and mbimx27:
allow fine control of UART4 and SDHC2 usage") added the Kconfig symbol
MACH_EUKREA_CPUIMX27_USEUART4. But it forgot to prepend CONFIG_ to the
use of its macro. Add that prefix now.

Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.
This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:

It moves a bunch of header files included in hardware.h and itself
from mach-imx/include/mach to mach-imx, and updates users to include
hardware.h rather than mach/hardware.h. The files in mach-imx/devices
will need to include "../hardware.h".

The I.MX platform is getting converted to use sparse IRQs. We are doing
this for all platforms over time, because this is one of the
requirements for building a multiplatform kernel, and generally a good
idea.

* Use the bool type as it applies here.
* Qualify otg_mode_host with __initdata since this variable is only used in this

indicating whether the param has been handled. See obsolete_checksetup() in

The patch makes necessary changes on gpio-mxc as below to turn it
into an upstanding gpio driver.
* Add a list to save all mx2 ports references, so that
mx2_gpio_irq_handler can walk through all interrupt status
registers
* Use readl/writel to replace mach-specific accessors
__raw_readl/__raw_writel
* Change mxc_gpio_init into mxc_gpio_probe function
* Move "struct mxc_gpio_port" into gpio-mxc.c, as it needs not to
be public at all, and also make some other cleanup on
plat-mxc/include/mach/gpio.h at the same time
And the patch then migrates mach-imx and mach-mx5 to the updated
driver by adding corresponding platform devices.

Most machine files include "devices-imxXX.h" which in turn includes
<mach/devices-common.h>. The latter already includes many headers

These were found by:

$ git grep -l 'devices-imx' arch/arm | xargs grep -f tmpfile -F
(but I kept linux/init.h, linux/kernel.h and linux/platform_device.h)

The boards are currently using otg_ulpi_create and mxc_ulpi_access_ops,
both are only present if CONFIG_USB_ULPI is set. To remove the need of

which expands to a static inline function if compiled without ulpi.

Recent clean of i.MX devices registration changed the i2C bus number
selected for our platform (Freescale start peripheral ID at 1, kernel
now start it at 0 so i.MX27's i2c 1 is kernel's i2c 0).
