Commit 5d2c154 (IMX: MX31: Cleanup include files and drop nasty #ifdef in drivers)
renamed mx31-imx-regs.h to imx-regs.h.
Change the file label accordingly.

Use the same method of the Linux kernel to print the MX31 silicon version on
boot.
Tested on a MX31PDK with a 2.0 silicon, where it shows:
CPU: Freescale i.MX31 rev 2.0 at 531 MHz

As exception among the i.MX processors, the i.MX31 has headers
without general names (mx31-regs.h, mx31.h instead of imx-regs.h and
clock.h). This requires several nasty #ifdef in the drivers to
include the correct header. The patch cleans up the driver and
renames the header files as for the other i.MX processors.

The patch add CONFIG_HW_WATCHDOG to be used
with the internal watchdog timer of the MX31
processor. Two function are exported for the
board maintainers:
mxc_hw_watchdog_enable
mxc_hw_watchdog_reset
The board maintainer can decide to use mxc_hw_watchdog_reset as
hw_watchdog_reset, or to implement his own function to reset
the watchdog.
The watchdog timer can be configured with CONFIG_SYS_WD_TIMER_SECS
(value in seconds). The MX31 allows values between 0.5
(CONFIG_SYS_WD_TIMER_SECS = 0) and 128 seconds.

This patch cleans driver code replacing all accesses
to registers with fixed offsets with a corresponding

The patch adds support for setting gpios to the
MX51 processor and change name to the corresponding
functions for MX31. In this way, it is possible to get rid
of nasty #ifdef switches related to the processor type.

The QONG module can be downsized and delivered
with 128MB instead of 256MB. The patch adds
run time support for the two different memory

This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.

Add support for Freescale's i.MX31 PDK board (a.k.a. 3 stack board).
This patch assumes that some other program performs the actual
NAND boot.

This patch adds the NAND SPL framework needed to boot i.MX31 boards
from NAND.
It has been tested on a i.MX31 PDK board with large page NAND. Small
page NANDs should work as well, but this has not been tested.
Note: The i.MX31 NFC uses a non-standard layout for large page NANDs,
whether this is compatible with a particular setup depends on how
the NAND device is programmed by the flash programmer (e.g. JTAG
debugger).
The patch is based on the work by Maxim Artamonov.

The "eet" variant of the imx31_phycore board has an OLED display, using a
s6e63d6 display controller on the first SPI interface, using GPIO57 as a
chip-select for it. With this configuration you can display 256 colour BMP
images in 16-bit RGB (RGB565) LCD mode.

Correct the mx31_gpio_mux() function to allow changing all i.MX31 IOMUX
contacts instead of only the first 256 ones as is the case prior to
this patch.
Add missing MUX_* macros and update board files to use the new macros.

This is an SPI driver for i.MX and MXC based SoCs from Freescale. So far
only implemented and tested on i.MX31, can with a modified register layout
and definitions be used for i.MX27, I think, MXC CPUs have similar SPI
controllers too.
