It is a pain to have to specify the value 10 in each call. Add a new
dectoul() function and update the code to use it.

It is a pain to have to specify the value 16 in each call. Add a new

Add a proper comment to simple_strtoul() while we are here.

Prior instantiating RNG we have to ensure if the CAAM job rings are
available. Avoid hardcoded job ring max size and use the definition at
fsl_sec.h

Prior calling sec_in32() we have to ensure CAAM clock is enabled, the
function sec_in32() is reading CAAM registers and if CAAM clock is disabled
the system will hang.

The CAAM output ring size register offset is currently defined in fsl_sec.h
as FSL_CAAM_ORSR_JRa_OFFSET, use this definition to avoid hardcoded value in
i.MX common code.

This code was originally developed by Raul Cardenas <raul.casas@nxp.com>
and modified to be applied in U-Boot imx_v2017.03.

i.MX7D has an a protection feature for Manufacturing process.
This feature uses asymmetric encryption to sign and verify
authenticated software handled between parties. This command
enables the use of such feature.
The private key is unique and generated once per device.
And it is stored in secure memory and only accessible by CAAM.
Therefore, the public key generation and signature functions
are the only functions available for the user.
The manufacturing-protection authentication process can be used to
authenticate the chip to the OEM's server.
Command usage:
Print the public key for the device.
- mfgprot pubk
Generates Signature over given data.
- mfgprot sign <data_address> <data_size>
