Introduce the DPAA2 mac driver, which manages Datapath
Media Access Control (DPMAC) objects discovered on the
MC bus.
This driver works as a proxy between phylib including phy
drivers and the Management Complex firmware. It receives
updates on link state changes from PHY lib and forwards
them to the Management Complex and receives interrupts
from the Management Complex whenever a request is made to
change the link state.

and caam/qi2 drivers sharing error.{c,h}.
However, the change is incomplete, since CRYPTO_DEV_FSL_CAAM should have

Add CAAM driver that works using the DPSECI backend, i.e. manages
DPSECI DPAA2 objects sitting on the Management Complex (MC) fsl-mc bus.
Data transfers (crypto requests) are sent/received to/from CAAM crypto
engine via Queue Interface (v2), this being similar to existing caam/qi.
OTOH, configuration/setup (obtaining virtual queue IDs, authorization
etc.) is done by sending commands to the MC f/w.
Note that the CAAM accelerator included in DPAA2 platforms still has
Job Rings. However, the driver being added does not handle access
via this backend. Kconfig & Makefile are updated such that DPAA2-CAAM
(a.k.a. "caam/qi2") driver does not depend on caam/jr or caam/qi
backends - which rely on platform bus support (ctrl.c).
Support for the following aead and authenc algorithms is also added
in this patch:
-aead:
gcm(aes)
rfc4106(gcm(aes))
rfc4543(gcm(aes))
-authenc:

CAAM RSA private key may have either of three representations.
1. The first representation consists of the pair (n, d), where the
components have the following meanings:
n the RSA modulus
d the RSA private exponent
2. The second representation consists of the triplet (p, q, d), where
the
components have the following meanings:
p the first prime factor of the RSA modulus n
q the second prime factor of the RSA modulus n
d the RSA private exponent
3. The third representation consists of the quintuple (p, q, dP, dQ,
qInv),
where the components have the following meanings:
p the first prime factor of the RSA modulus n
q the second prime factor of the RSA modulus n
dP the first factors's CRT exponent
dQ the second factors's CRT exponent
qInv the (first) CRT coefficient
The benefit of using the third or the second key form is lower
computational cost for the decryption and signature operations.
This patch adds support for the third RSA private key
representations and extends caampkc to use the fastest key when all
related components are present in the private key.

The way Job Ring platform devices are created and released does not
allow for multiple create-release cycles.
JR0 Platform device creation error
JR0 Platform device creation error
caam 2100000.caam: no queues configured, terminating
caam: probe of 2100000.caam failed with error -12
The reason is that platform devices are created for each job ring:
for_each_available_child_of_node(nprop, np)
if (of_device_is_compatible(np, "fsl,sec-v4.0-job-ring") ||
of_device_is_compatible(np, "fsl,sec4.0-job-ring")) {
ctrlpriv->jrpdev[ring] =
of_platform_device_create(np, NULL, dev);
which sets OF_POPULATED on the device node, but then it cleans these up:
/* Remove platform devices for JobRs */
for (ring = 0; ring < ctrlpriv->total_jobrs; ring++) {
if (ctrlpriv->jrpdev[ring])
of_device_unregister(ctrlpriv->jrpdev[ring]);
}
which leaves OF_POPULATED set.
Use of_platform_populate / of_platform_depopulate instead.
This allows for a bit of driver clean-up, jrpdev is no longer needed.
Logic changes a bit too:
-exit in case of_platform_populate fails, since currently even QI backend
depends on JR; true, we no longer support the case when "some" of the JR
DT nodes are incorrect
-when cleaning up, caam_remove() would also depopulate RTIC in case
it would have been populated somewhere else - not the case for now

interfering with existing caam/jr driver.

CAAM engine supports two interfaces for crypto job submission:
-job ring interface - already existing caam/jr driver
-Queue Interface (QI) - caam/qi driver added in current patch
QI is present in CAAM engines found on DPAA platforms.
QI gets its I/O (frame descriptors) from QMan (Queue Manager) queues.
This patch adds a platform device for accessing CAAM's queue interface.
The requests are submitted to CAAM using one frame queue per
cryptographic context. Each crypto context has one shared descriptor.
This shared descriptor is attached to frame queue associated with
corresponding driver context using context_a.
The driver hides the mechanics of FQ creation, initialisation from its
applications. Each cryptographic context needs to be associated with
driver context which houses the FQ to be used to transport the job to
CAAM. The driver provides API for:
(a) Context creation
(b) Job submission
(c) Context deletion
(d) Congestion indication - whether path to/from CAAM is congested
The driver supports affining its context to a particular CPU.
This means that any responses from CAAM for the context in question
would arrive at the given CPU. This helps in implementing one CPU
per packet round trip in IPsec application.
The driver processes CAAM responses under NAPI contexts.
NAPI contexts are instantiated only on cores with affined portals since
only cores having their own portal can receive responses from DQRR.
The responses from CAAM for all cryptographic contexts ride on a fixed
set of FQs. We use one response FQ per portal owning core. The response
FQ is configured in each core's and thus portal's dedicated channel.
This gives the flexibility to direct CAAM's responses for a crypto
context on a given core.

If we register the DMA API debug notification chain to
receive platform bus events:
dma_debug_add_bus(&platform_bus_type);
we start receiving warnings after a simple test like "modprobe caam_jr &&
modprobe caamhash && modprobe -r caamhash && modprobe -r caam_jr":
platform ffe301000.jr: DMA-API: device driver has pending DMA allocations while released from device [count=1938]
One of leaked entries details: [device address=0x0000000173fda090] [size=63 bytes] [mapped with DMA_TO_DEVICE] [mapped as single]
It turns out there are several issues with handling buf_dma (mapping of buffer
holding the previous chunk smaller than hash block size):
-detection of buf_dma mapping failure occurs too late, after a job descriptor
using that value has been submitted for execution
-dma mapping leak - unmapping is not performed in all places: for e.g.
in ahash_export or in most ahash_fin* callbacks (due to current back-to-back
implementation of buf_dma unmapping/mapping)
Fix these by:
-calling dma_mapping_error() on buf_dma right after the mapping and providing
an error code if needed
-unmapping buf_dma during the "job done" (ahash_done_*) callbacks

HW S/G generation does not work properly when the following conditions
are met:
-src == dst
-src/dst is S/G
-IV is right before (contiguous with) the first src/dst S/G entry
since "iv_contig" is set to true (iv_contig is a misnomer here and
it actually refers to the whole output being contiguous)

leaving it set to init value (0).

Refactor the generation of the authenc, ablkcipher shared descriptors
and exports the functionality, such that they could be shared
with the upcoming caam/qi (Queue Interface) driver.

Remove dependency on CRYPTO_DEV_FSL_CAAM where superfluous:
depends on CRYPTO_DEV_FSL_CAAM && CRYPTO_DEV_FSL_CAAM_JR
is equivalent to
depends on CRYPTO_DEV_FSL_CAAM_JR
since CRYPTO_DEV_FSL_CAAM_JR depends on CRYPTO_DEV_FSL_CAAM.

A few descriptor commands are generated using generic
inline append "append_cmd" function.
Rewrite them using specific inline append functions.

For authenc / stitched AEAD algorithms, check independently
each of the two (authentication, encryption) keys whether inlining
is possible.
Prioritize the inlining of the authentication key, since the length
of the (split) key is bigger than that of the encryption key.
For the other algorithms, compute only once per tfm the remaining
available bytes and decide whether key inlining is possible
based on this.

Shared descriptors used by ahash_final() and ahash_finup()

The pointer to the descriptor buffer is not touched,
it always points to start of the descriptor buffer.
Thus, make it const.
