SPDX: Convert all of our single license tags to Linux Kernel style

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.

fsl: Secure Boot: Enable IE (Key extention) Feature

For validating images from uboot (Such as Kernel Image), either keys
from SoC fuses can be used or keys from a verified table of public
keys can be used. The latter feature is called IE Key Extension
Feature.

For Layerscape Chasis 3 based platforms, IE table is validated by
Bootrom and address of this table is written in scratch registers 13
and 14 via PBI commands.

Following are the steps describing usage of this feature:

1) Verify IE Table in ISBC phase using keys stored in fuses.
2) Install IE table. (To be used across verification of multiple
images stored in a static global structure.)
3) Use keys from IE table, to verify further images.

Enable hardware crypto operations in SPL using SEC block.
In case of Secure Boot, PAMU is not bypassed. For allowing SEC block
access to CPC configured as SRAM, configure PAMU.

SECURE BOOT: support for validation of dynamic image

Some images to be validated are relocated to a dynamic
address at run time. So, these addresses cannot be known
befor hand while signing the images and creating the header
offline.
So, support is required to pass the image address to the
validate function as an argument.
If an address is provided to the function, the address
field in Header is not read and is treated as a reserved
field.

SECURE BOOT: Add command for validation of images

1. esbc_validate command is meant for validating header and
signature of images (Boot Script and ESBC uboot client).
SHA-256 and RSA operations are performed using SEC block in HW.
This command works on both PBL based and Non PBL based Freescale
platforms.
Command usage:
esbc_validate img_hdr_addr [pub_key_hash]
2. ESBC uboot client can be linux. Additionally, rootfs and device
tree blob can also be signed.
3. In the event of header or signature failure in validation,
ITS and ITF bits determine further course of action.
4. In case of soft failure, appropriate error is dumped on console.
5. In case of hard failure, SoC is issued RESET REQUEST after
dumping error on the console.
6. KEY REVOCATION Feature:
QorIQ platforms like B4/T4 have support of srk key table and key
revocation in ISBC code in Silicon.
The srk key table allows the user to have a key table with multiple
keys and revoke any key in case of particular key gets compromised.
In case the ISBC code uses the key revocation and srk key table to
verify the u-boot code, the subsequent chain of trust should also
use the same.
6. ISBC KEY EXTENSION Feature:
This feature allows large number of keys to be used for esbc validation
of images. A set of public keys is being signed and validated by ISBC
which can be further used for esbc validation of images.
