Current driver doesn't check if the destination pointer is NULL.
This cause the data from the FIFO to be stored inside the internal
SDRAM ( address 0 ).
The patch add simple check if the destination pointer is NULL.

U-Boot binary has grown in such a way that it goes beyond the reserved
area for the environment variables.
Running "saveenv" causes U-Boot to hang because of this overlap.
Fix this problem by increasing the CONFIG_ENV_OFFSET size.
Also, in order to prevent this same problem in the future, use
CONFIG_BOARD_SIZE_LIMIT, which will detect the overlap in build-time.
CONFIG_BOARD_SIZE_LIMIT does not accept math expressions, so declare
CONFIG_ENV_OFFSET with its direct value instead.

Without this change it is possible that Vybrid's NFC driver malloc() call
will obtain some memory used (and correctly free'd) by some previous
driver (in this case pinctrl for Vybrid).
As a result some fields of struct nfc - in out case mtd->_get_device - are
"pre initialized" with some random values.
On the latter stage of booting, when e.g. somebody calls 'mtdparts default'
the "data abort" is observed when __get_mtd_device() function is called.
The mtd->_get_device pointer is not NULL and wrong value is referenced.

Currently, U-Boot ignores the BBT stored in the last 4 blocks of NAND
flash because the NAND_BBT_USE_FLASH flag is not set. This leads to
two issues:
* U-Boot silently uses a memory-only BBT which is initialized with all
blocks marked as good. This means, actual bad blocks are marked good
and U-Boot might try writing to or reading from them.
* The BBT in flash, which will be created once Linux boots up, is not
off limits for a driver ontop, like UBI. While it does not seem to
consistently produce an error, sometimes UBI will fail to attach
because the BBT blocks obviously don't contain valid UBI data.
To fix this, this patch sets the CONFIG_SYS_NAND_USE_FLASH_BBT option,
which is used in ./drivers/mtd/nand/raw/mxs_nand.c to decide whether
a BBT in flash is used.

Current implementation of hab_auth_img command needs ivt_offset to
authenticate the image. But ivt header is placed at the end of image
date after padding.
This leaves the usage of hab_auth_img command to fixed size or static
offset for ivt header. New function "get_image_ivt_offset" is introduced
to find the ivt offset during runtime. The case conditional check in this
function is same as boot_get_kernel in common/bootm.c
With this variable length image e.g. FIT image with any random size can
have IVT at the end and ivt_offset option can be left optional
Can be used as "hab_auth_img $loadaddr $filesize" from u-boot script

Introduce two board level callback functions to FIT image loading process, and
a SPL_FIT_FOUND flag to differentiate FIT image or RAW image.
Implement functions in imx common SPL codes to call HAB funtion
to authenticate the FIT image. Generally, we have to sign multiple regions
in FIT image:
1. Sign FIT FDT data (configuration)
2. Sign FIT external data (Sub-images)
Because the CSF supports to sign multiple memory blocks, so that we can use one
signature to cover all regions in FIT image and only authenticate once.
The authentication should be done after the entire FIT image is loaded into
memory including all sub-images.
We use "-p" option to generate FIT image to reserve a space for FIT IVT
and FIT CSF, also this help to fix the offset of the external data (u-boot-nodtb.bin,
ATF, u-boot DTB).
The signed FIT image layout is as below:
--------------------------------------------------
| | | | | | | |
| FIT | FIT | FIT | | U-BOOT | ATF | U-BOOT |
| FDT | IVT | CSF | | nodtb.bin | | DTB |
| | | | | | | |

Using ulong is wrong as its size depends on the Host CPU architecture
(32-bit vs. 64-bit) although the Cortex-M4 is always 32-bit.

While migrating individual status led usages to Kconfig stuff,
a (random) value was introduced for this board which does not
work but produces the following error message during boot:
__led_init: failed requesting GPIO59!
Since Kconfig does not seem to accept a define as this point,
but the mxs gpio driver requires not only a simple integer value,
we need to use the plain value of MX23_PAD_SSP1_DETECT__GPIO_2_1.
