Several platforms create IOMEM defines for casting to 'void __iomem *',
and other platforms are incorrectly using __io() macro for the same
purpose. This creates a common definition and removes all the platform
specific versions. Rather than try to make linux/io.h and asm/io.h
assembly safe, the assembly version of IOMEM is moved into
asm/assembler.h.

Use a static mapping for TZIC to get rid of the duplicated code for
ioremap and the corresponding error handling. This is already done on
i.MX50.

This patch also removes TZIC mapping for i.mx51 TO1 since
there is no support for TO1 now since the following commit:

Signed-off-by: NSascha Hauer <s.hauer@pengutronix.de>

To be able to compile e.g. i.MX31 and i.MX51 in a single kernel image
the ioremap quirk needs a runtime check.

While touching this code make the comment more understandable by adding
a sentence from the commit log that introduced it
(eadefeff ([ARM] MX3: Use ioremap wrapper to map SoC devices nonshared)).

As mach/io.h now uses cpu_is_ some header reshuffling in mach/hardware.h
was necessary. (mach/mx27.h and mach/mx31.h #include <linux/io.h> which
#includes <mach/io.h>. So mach/mxc.h which provides the cpu_is_ macros
needs to be included before mach/mx27.h and mach/mx31.h.)

only had 4 devices (2x UART, sdhc, watchdog).

Now only the virtual addresses [0xf4000000, 0xf5ffffff] are used for
static per-SoC mappings.  The few mappings of whole chip selects are
moved accordingly.

The now wrong defines for virtual base addresses are removed.
Signed-off-by: NUwe Kleine-König <u.kleine-koenig@pengutronix.de>

This makes less code rely on the virtual constants.

To further simplify code and reduce the needed boilerplate when
defining the static mappings a new helper macro is defined in
mach/hardware.h.

This makes it more assembler friendly and allows it to be used in situation
that need an unsigned long and not a pointer.  Also the naming is
clearer.  IOMEM is introduced without IMX_ prefix as it is used this way
in more than one ARM subarch and it might become globally available
soon.

This patch separates the current code into i.MX2 and i.MX3 and modifies
the Kconfig files to reflect this separation in the menus.

Things happend since last review:
 - make i.MX3 compile again
 - fix some structure names to be conform with all the shared/common
