./build/picopi/release/bl2/imx_snvs.o:(.bss.__packed+0x0): multiple definition of `__packed';
./build/picopi/release/bl2/imx_caam.o:(.bss.__packed+0x0): first defined here

__packed was intended to be the attribute macro from cdefs.h, not an
object of the structure type.

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

This patch defines the most basic part of the CAAM and the only piece of
the CAAM silicon we are really interested in, in ATF, the CAAM control
structure.

The CAAM itself is a huge address space of some 32k, way out of scope for
the purpose we have in ATF.

This patch adds a simple CAAM init function that assigns ownership of the
CAAM job-rings to the non-secure MID with the ownership bit set to
non-secure.

This will allow later logic in the boot process such as OPTEE, u-boot and
Linux to assign job-rings as appropriate, restricting if necessary but
leaving open the main functionality of the CAAM to the Linux NS runtime.
