bee7bdf11f crypto: cavium/nitrox - Fix HW family part name format
This patch fixes the NITROX-V family part name format. The fix includes
ZIP core performance (feature option) in the part name to differentiate
various HW devices. The complete HW part name format is mentioned below

Part name: CNN55<core option>-<freq>BG676-<feature option>-<rev>

df80bfd343 crypto: caam/jr - update gcm detection logic
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.

877b5691f2 crypto: shash - remove shash_desc::flags
The flags field in 'struct shash_desc' never actually does anything.
The only ostensibly supported flag is CRYPTO_TFM_REQ_MAY_SLEEP.
However, no shash algorithm ever sleeps, making this flag a no-op.

With this being the case, inevitably some users who can't sleep wrongly
pass MAY_SLEEP.  These would all need to be fixed if any shash algorithm
actually started sleeping.  For example, the shash_ahash_*() functions,
which wrap a shash algorithm with the ahash API, pass through MAY_SLEEP
from the ahash API to the shash API.  However, the shash functions are
called under kmap_atomic(), so actually they're assumed to never sleep.

Even if it turns out that some users do need preemption points while
hashing large buffers, we could easily provide a helper function
crypto_shash_update_large() which divides the data into smaller chunks
and calls crypto_shash_update() and cond_resched() for each chunk.  It's
not necessary to have a flag in 'struct shash_desc', nor is it necessary
to make individual shash algorithms aware of this at all.

Therefore, remove shash_desc::flags, and document that the
crypto_shash_*() functions can be called from any context.

75f2222832 crypto: nx - don't abuse shash MAY_SLEEP flag
The nx driver uses the MAY_SLEEP flag in shash_desc::flags as an
indicator to not retry sending the operation to the hardware as many
times before returning -EBUSY.  This is bogus because (1) that's not
what the MAY_SLEEP flag is for, and (2) the shash API doesn't allow
failing if the hardware is busy anyway.

For now, just make it always retry the larger number of times.  This
doesn't actually fix this driver, but it at least makes it not use the
shash_desc::flags field anymore.  Then this field can be removed, as no
other drivers use it.

626ddb2fbe crypto: powerpc - convert to use crypto_simd_usable()
Replace all calls to in_interrupt() in the PowerPC crypto code with
!crypto_simd_usable().  This causes the crypto self-tests to test the
no-SIMD code paths when CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y.

The p8_ghash algorithm is currently failing and needs to be fixed, as it
produces the wrong digest when no-SIMD updates are mixed with SIMD ones.

0edf8593eb crypto: cavium - remove bogus code handling cryptd
The cavium crypto driver adds 'sizeof(struct ablkcipher_request)' to its
request size because "the cryptd daemon uses this memory for request_ctx
information".  This is incorrect and unnecessary; cryptd doesn't require
wrapped algorithms to reserve extra request space.  So remove this.

Also remove the unneeded memset() of the tfm context to 0.
It's already zeroed on allocation.

33d69455e4 crypto: caam - limit AXI pipeline to a depth of 1
Some i.MX6 devices (imx6D, imx6Q, imx6DL, imx6S, imx6DP and imx6DQ) have
an issue wherein AXI bus transactions may not occur in the correct order.
This isn't a problem running single descriptors, but can be if running
multiple concurrent descriptors. Reworking the CAAM driver to throttle
to single requests is impractical, so this patch limits the AXI pipeline
to a depth of one (from a default of 4) to preclude this situation from
occurring.
This patch applies to known affected platforms.

c23116e48a crypto: caam/jr - Remove extra memory barrier during job ring enqueue
In caam_jr_enqueue(), a write barrier is needed to order stores to job
ring slot before declaring addition of new job into input job ring.
The register write is done using wr_reg32() which internally uses
iowrite32() for write operation. The api iowrite32() issues a write
barrier before issuing write operation. Therefore, the wmb() preceding
wr_reg32() can be safely removed.

1b30b989cb crypto: caam/jr - Removed redundant vars from job ring private data
For each job ring, the variable 'ringsize' is initialised but never
used. Similarly variables 'inp_ring_write_index' and 'head' always track
the same value and instead of 'inp_ring_write_index', caam_jr_enqueue()
can use 'head' itself. Both these variables have been removed.

a118dfa0db crypto: caam/jr - Remove spinlock for output job ring
For each job ring pair, the output ring is processed exactly by one cpu
at a time under a tasklet context (one per ring). Therefore, there is no
need to protect a job ring's access & its private data structure using a
lock. Hence the lock can be removed.
