GCM detection logic has to change for two reasons: -some CAAM instantiations with Era < 10, even though they have AES LP, they now support GCM mode -Era 10 upwards, there is a dedicated bit in AESA_VERSION[AESA_MISC] field for GCM support For Era 9 and earlier, all AES accelerator versions support GCM, except for AES LP (CHAVID_LS[AESVID]=3) with revision CRNR[AESRN] < 8. For Era 10 and later, bit 9 of the AESA_VERSION register should be used to detect GCM support in AES accelerator. Note: caam/qi and caam/qi2 are drivers for QI (Queue Interface), which is used in DPAA-based SoCs; for now, we rely on CAAM having an AES HP and this AES accelerator having support for GCM.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
