The make macro to check if the binary exceeds the board size limit is
taken straight from the root Makefile.

Without this and e.g. enabled EFI Vybrid fails booting as the regular
size limit check does not take the final u-boot.imx binary size into
account which is bigger due to alignment as well as IMX header stuff.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

Each imx image is created by a separate sub-make and during this process
the mkimage config file is run though cpp.

The cpp output is to the same file no matter what imx image is being
created.

This means if two imx images are generated in parallel they will attempt
to independently produce the same pre-processed mkimage config file at
the same time.

Avoid the problem by making the pre-processed config file name unique
based on the imx image it will be used in.  This way each image will
create a unique config file and they won't clobber each other when run
in parallel.

This should fixed the build bug referenced in b5b0e4e3 ("imximage:
Remove failure when no IVT offset is found").

Freescale's SEC block has built-in Data Encryption
Key(DEK) Blob Protocol which provides a method for
protecting a DEK for non-secure memory storage.
SEC block protects data in a data structure called
a Secret Key Blob, which provides both confidentiality
and integrity protection.
Every time the blob encapsulation is executed,
a AES-256 key is randomly generated to encrypt the DEK.
This key is encrypted with the OTP Secret key
from SoC. The resulting blob consists of the encrypted
AES-256 key, the encrypted DEK, and a 16-bit MAC.

During decapsulation, the reverse process is performed
to get back the original DEK. A caveat to the blob
decapsulation process,  is that the DEK is decrypted
in secure-memory and can only be read by FSL SEC HW.
The DEK is used to decrypt data during encrypted boot.

Commands added
--------------
  dek_blob - encapsulating DEK as a cryptgraphic blob

Commands Syntax
---------------
  dek_blob src dst len
