The IIM module uses two drivers, one for the general IIM
module and one for the individual banks.
This patch turns this into a single driver to ease registration
of the resources. This changes the user visible behaviour in
the way that the explicit_sense_enable and permanent_write_enable
device parameters are no longer bank specific but for the
whole device. Also, the IIM module supports a maximum of
8 fuse banks, with these patch all of them are registered, even
if they are not present in a SoC.

The i.MX Processors support two different boot modes, the internal
boot mode and the external boot mode. Traditionally the external
NAND boot mode is handled in drivers/mtd/nand and the internal
boot mode is handled in arch/arm/mach-imx. This patch consolidates
the handling of both boot modes in arch/arm/mach-imx so that
the user does not have to look in the mtd kconfig section for
booting from NAND. Also, selecting between internal and external
boot mode now is a clear choice.
The external NAND boot mode has been independent of the mtd nand
driver, but as the code was contained in the NAND driver it was
not possible to support booting from NAND without a mtd nand driver.
This is changed with this patch.

This driver provides an interface for programming and sensing the IIM fusebox
which is present on some i.MX chips.
Since the IIM io addresses of the controlling registers and each fuse bank are
are not contiguous the driver implementation uses two drivers, imx_iim, and
imx_iim_bank. The imx_iim is the "parent" driver for a device holding the
map_base address of the control registers. The imx_iim_bank driver is for
child devices holding the map_base of each fuse bank. The platform code then,
instantiate one imx_iim_bank device per fuse bank.
Fuses blow is a dangerous operation. Thus, the fuses blow functionality can be
disabled independently at configuration time. On run time this functionality
must be enabled explicitly by setting the permanent_write_enable parameter.
