The conversion of mx31pdk to SPL NAND fixed the boot issue, but we start seeing

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 because its FCB is more complicated.

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.

make never uses the SHELL variable from the environment. Instead, it
uses /bin/sh, or the value assigned to the SHELL variable by the Makefile. This
makes the export of the SHELL variable useless for sub-makes (but still useful
for the environment of recipes). However, we want all makes to use the same
shell.
This patch fixes this issue by moving the SHELL variable setup and export to the
top config.mk, so that all Makefile-s including it use the same shell.
Since BASH is used by default, this makes it possible to use things
like 'echo -e ...' in sub-makes, which would otherwise fail e.g. with /bin/sh
symlinked to /bin/dash on Ubuntu.

Give more flexibility to define configs that can be interpreted by make, e.g. to
define fallback values of configs like in the example below.
Before this change, the config lines:
#define CONFIG_SPL_MAX_SIZE 2048
#define CONFIG_SPL_PAD_TO CONFIG_SPL_MAX_SIZE
would have been changed in autoconfig.mk into:
CONFIG_SPL_MAX_SIZE=2048
CONFIG_SPL_PAD_TO="CONFIG_SPL_MAX_SIZE"
Hence, a make recipe using as an argument to $(OBJCOPY):
--pad-to=$(CONFIG_SPL_PAD_TO)
would have issued:
--pad-to="CONFIG_SPL_MAX_SIZE"
which means nothing for $(OBJCOPY) and makes it fail.
Thanks to this change, the config lines above are changed in autoconfig.mk into:
CONFIG_SPL_MAX_SIZE=2048
CONFIG_SPL_PAD_TO=$(CONFIG_SPL_MAX_SIZE)
Hence, the make recipe above now issues:
--pad-to=2048
as expected from the defined config.

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
to store the environment variables, would lead to the following error:
NAND bus width 16 instead 8 bit
No NAND device found!!!
0 MiB
Use CONFIG_SYS_NAND_BUSWIDTH_16BIT symbol to decide the bus width.
If it is defined in the board file, then consider 16-bit NAND bus-width,
otherwise assume 8-bit NAND is used.
This also aligns with Documentation/devicetree/bindings/mtd/nand.txt, which
states:
nand-bus-width : 8 or 16 bus width if not present 8

In the case of booting from certain peripherals, such as UART, we must
not see what the device descriptor says for RAW or FAT mode because in
addition to being nonsensical, it leads to a hang. This is why we have
a test currently for the boot mode being within range. The problem
however is that on some platforms we get MMC2_2 as the boot mode and not
the defined value for MMC2, and in others we get the value for MMC2_2.
This is required to fix eMMC booting on omap5_uevm.
