All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.
The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.
The exceptions are files that are imported from other projects:
- CryptoCell driver
- dt-bindings folders
- zlib headers

The High Assurance Boot or HAB is an on-chip method of providing a
root-of-trust from the reset vector to subsequent stages in the bootup
flow of the Cortex-A7 on the i.MX series of processors.
This patch adds a simple header file with pointer offsets of the provided
set of HAH API callbacks in the BootROM.
The relative offset of the function pointers is a constant and known
quantum, a software-contract between NXP and an implementation which is
defined in the NXP HAB documentation.
All we need is the correct base offset and then we can map the set of
function pointers relative to that offset.
imx_hab_arch.h provides the correct offset and the imx_hab.h hooks the
offset to the pre-determined callbacks.
