imx: Kconfig: Reduce default CONFIG_CSF_SIZE

The default CSF_SIZE defined in Kconfig is too high and SPL cannot
fit into the OCRAM in certain cases.

The CSF cannot achieve 0x2000 length when using RSA 4K key which is
the largest key size supported by HABv4.

According to AN12056 "Encrypted Boot on HABv4 and CAAM Enabled Devices"
it's recommended to pad CSF binary to 0x2000 and append DEK blob to
deploy encrypted boot images.

As the maximum DEK blob size is 0x58 we can reduce CSF_SIZE to 0x2060
which should cover both CSF and DEK blob length.

Update default_image.c and image.c to align with this change and avoid
a U-Boot proper authentication failure in HAB closed devices:

5 years agomx53loco: Fix U-Boot corruption after saving the environment

mx53loco: Fix U-Boot corruption after saving the environment

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.
