This patch adds the Kernel support for the caam-keygen user-space
application. It has two IOCTL calls for key and blob generation and
import a black key from a blob.
This support is included in CRYPTO_DEV_FSL_CAAM_TK_API (tagged key
support).

CAAM's Black Key mechanism is intended for protection
of user keys against bus snooping. This automatically
encapsulates and decapsulates cryptographic keys ''on-the-fly''
in an encrypted data structure called a Black Key.
Before a value is copied from a Key Register to memory,
CAAM will automatically encrypt the key as a Black Key
(encrypted key) using the current value in the JDKEKR or
TDKEKR as the encryption key.
CAAM's built-in Blob Protocol provides a method for protecting
user-defined data across system power cycles. CAAM protects data
in a data structure called a Blob, which provides both confidentiality
and integrity protection. The data to be protected is encrypted so that
it can be safely placed into non-volatile storage before the SoC is
powered down.
This patch includes the support to generate a black key from random or
from a plaintext. Also one can encapsulate it into a blob or decapsulate
a black key from a blob.
The key and blob generation descriptors are exported into a separate file,
such that they could be shared with other interfaces (qi, qi2).
This feature has support only for black keys, encapsulated in
black blobs in General Memory.
In caamkeyblob_test.c file is a test that validates the above
operations: create a black key from plaintext or from random,
encapsulate and decapsulate a blob and compare the obtained black key.
This test is configured as a kernel module.

Tagged keys are keys that contain metadata indicating what
they are and how to handle them using the new added tag_object API.
A tag object represents the metadata (or simply a header/configuration)
and the actual data (e.g. black key) obtained from hardware.
The support, for tagged keys, to skcipher algorithms, is done by
adding new transformations, with tk prefix to distinguish
between plaintext and tagged keys.
The tk_ transformations can be used directly by their name:
struct sockaddr_alg sa = {
.salg_family = AF_ALG,
.salg_type = "skcipher", /* this selects the symmetric cipher */
.salg_name = "tk(cbc(aes))" /* this is the cipher name */
};
or for dm-crypt, e.g. using dmsetup:
dmsetup -v create encrypted --table "0 $(blockdev --getsz /dev/mmcblk2p10)
crypt capi:tk(cbc(aes))-plain :32:logon:seckey 0 /dev/mmcblk2p10 0 1
sector_size:512".
tk_ transformations will know how to handle tagged keys, by loading the
proper settings for KEY command.
The API expects that the object (the actual data) from a tag object
to be a buffer (defined by address and size).

for EP0IN may occur since it is DMULT mode, the DMA does not stop
until TRBERR has met.
