> In certain i.MX devices the encrypted boot image is failing to boot.
> According to AN12056 "Encrypted Boot on HABv4 and CAAM Enabled Devices"
> it's necessary to pad CSF to 0x2000 and append DEK blob.
> In this case the total image size in boot data structure must cover the
> entire binary otherwise the dek_blob won't be copied to memory and image
> won't be decrypted.
> Increase CSF_SIZE to 0x4000 to avoid such issue when booting encrypted
> boot images.
