This is broken on big endian systems since:
943b271 cfi_flash: support of u32 cmd
I looked over it and I *think* that the function was correct
for both big and little endian systems before this patch.
To support u32 cmd we only have to change the data type of
the command from u8 to u32.

To allow for some generic io accessors introduce io.h and use
this instead of asm/io.h throughout the tree.

The nand controller on i.MX51/53 uses two base addresses. Instead
of hardcode the second address use the new shiny resources two specify
it.

Based on the Linux driver. Tested with m25p80 with CS in GPIO mode.
Clock setting support is ad-hoc as the corresponding mach is not using
the generic clock infrastructure.

This code was tested barely with m25p80 driver, reading jedec id and some data
from the chip worked fine.

Some NOR flash chips have commands with length greater than the maximum

This patch adds the m25p80 driver. It has been ported from
Linux. MTD code has been removed. It has been tested with
a m25p40 chip and the Altera SPI master driver.

Otherwise, when a non active device is unregistered, we call

this will also fix the clock support as we now switch to allocated generic
device
as we can need to associate the clock and the device but the driver is probe
before the association
we also change the atmel serial name to "atmel_usart" to simplify sharing with
linux
