for SPI NOR flash.
CONFIG_MACH_DREAMPLUG defined in include/configs/dreamplug.h until Linus's

can be removed from include/configs/dreamplug.h.

Currently there are two config options for building a U-boot binary for MX31PDK:
make mx31pdk_config
or,
make mx31pdk_nand_config
mx31pdk_config was developed first when no NAND SPL support was available for
MX31 and it requires that the U-boot binary is loaded into RAM via JTAG and it
forces SKIP_LOWLEVEL_INIT.
mx31pdk_nand_config was added later and it allows booting from NAND Flash.
Leave just one config option called mx31pdk so that it produces a binary that can boot from NAND Flash.

mx31: provide readable WEIM CS accessor
setup_weimcs() and some macros are added to support the setup
for i.MX31 WEIM chip selects. As a compromise between verbosity
and readability an ASCII-art'ish bit comment is used instead of
bitfields.
All i.MX31 boards have been patched to use this approach using a
helper program to verify the changes.

This adds support for changing pinmux functions of pin groups. This is done

This library provides useful functions to drivers which want to use
the fdt to control their operation. Functions are provided to:
- look up and enumerate a device type (for example assigning i2c bus 0,
i2c bus 1, etc.)
- decode basic types from the fdt, like addresses and integers
While this library is not strictly necessary, it helps to minimise the
changes to a driver, in order to make it work under fdt control. Less
code is required, and so the barrier to switch drivers over is lower.
Additional functions to read arrays and GPIOs could be made available
here also.

Support this by moving the call to run_post(POST_ROM) to run earlier,
