to DM, such as warp7, to fail to boot.

As explained by Lukas Auer:

"With the patch, U-Boot probes the drivers for devices under simple-bus
device tree nodes in the pre-relocation device model. The default value
of CONFIG_SYS_MALLOC_F_LEN (0x4000) leaves U-Boot with not enough memory to

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:

Authenticate image from DDR location 0x877fffc0...
