Greetings,
I've been fighting with SPL passing not boot_params properly to u-boot on
OMAP4. There are many layers to this onion but I've tracked the bulk of the
problem down to the following issues.
--- SPL ---
arch/arm/cpu/armv7/omap-common/hwinit-common.c sets a pointer to the SPL's
&boot_p
Thanks, I'll be glad to finally see this patch applied.

Hi Michael,
(please wrap your line around 70 chars max)
I won't comment on the 'u-boot' part of your message as it is quite
SPL-vs-U-Boot- and OMAP-specific, and I prefer to leave this to people
better suited for this. However, on the low level init front:

Introduce CONFIG_SYS_NAND_BUSWIDTH_16BIT option so that other NAND controller
drivers could use it when a 16-bit NAND is deployed.
drivers/mtd/nand/ndfc has CONFIG_SYS_NDFC_16BIT, so just rename it, so that
other NAND drivers could reuse the same symbol.

From: Fabio Estevam
Currently is_16bit_nand() is a per SoC function and it decides the bus nand
width by reading some boot related registers.
This method works when NAND is the boot medium, but does not work if another
boot medium is used. For example: booting from a SD card and then using NAND

This image combines the SPL with the i.MX header and U-Boot. This is a
convenient way of having a single image to program on some boot devices.
The i.MX header has to be added to the SPL before appending U-Boot, so that the
boot ROM loads only the SPL.

This image combines the SPL with the i.MX header, the FCB and U-Boot.
For i.MX25/35/51, the FCB is ignored by the boot ROM, so this image is just
useful because it can be programmed on a NAND Flash page boundary.
For i.MX53, the FCB is required by the boot ROM.
This does not support i.MX6 so far
Following the removal of the smdk6400 board, the MMU setup code in
