Commit d2825fa936 ("crypto: sm3,sm4 - move into crypto directory") moves
the SM3 and SM4 stand-alone library and the algorithm implementation for
the Crypto API into the same directory, and the corresponding relationship
of Kconfig is modified, CONFIG_CRYPTO_SM3/4 corresponds to the stand-alone
library of SM3/4, and CONFIG_CRYPTO_SM3/4_GENERIC corresponds to the
algorithm implementation for the Crypto API. Therefore, it is necessary
for this module to depend on the correct algorithm.

The Mediatek accelerator driver calls into a dynamically allocated
skcipher of the ctr(aes) variety to perform GCM key derivation, which
involves AES encryption of a single block consisting of NUL bytes.
There is no point in using the skcipher API for this, so use the AES
library interface instead.

crypto test module passes zero length vectors as test input to sha-1 and
sha-256. To provide correct output for these vectors, hash zero support
has been added as in other crypto drivers.

Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Process small blocks using the fallback cipher, as a workaround for an
observed failure (DMA-related, apparently) when computing the GCM ghash
key. This brings a speed gain as well, since it avoids the latency of
using the hardware engine to process small blocks.
Using software for all 16-byte requests would be enough to make GCM
work, but to increase performance, a larger threshold would be better.
Measuring the performance of supported ciphers with openssl speed,
software matches hardware at around 768-1024 bytes.
Considering the 256-bit ciphers, software is 2-3 times faster than qce
at 256-bytes, 30% faster at 512, and about even at 768-bytes. With
128-bit keys, the break-even point would be around 1024-bytes.
This adds the 'aes_sw_max_len' parameter, to set the largest request
length processed by the software fallback. Its default is being set to
512 bytes, a little lower than the break-even point, to balance the cost
in CPU usage.

Fix up inconsistent usage of upper and lowercase letters in "Exynos"
name.
"EXYNOS" is not an abbreviation but a regular trademarked name.
Therefore it should be written with lowercase letters starting with
capital letter.
The lowercase "Exynos" name is promoted by its manufacturer Samsung
Electronics Co., Ltd., in advertisement materials and on website.

Allow the user to choose whether to build support for all algorithms
(default), hashes-only, or skciphers-only.
The QCE engine does not appear to scale as well as the CPU to handle
multiple crypto requests. While the ipq40xx chips have 4-core CPUs, the
QCE handles only 2 requests in parallel.
Ipsec throughput seems to improve when disabling either family of
algorithms, sharing the load with the CPU. Enabling skciphers-only
appears to work best.

Currently CONFIG_CRYPTO_DEV_SAFEXCEL=y implicitly depends on
CONFIG_HAS_IOMEM=y; consequently, on architectures without IOMEM we get
the following build error:
ld: drivers/crypto/inside-secure/safexcel.o: in function `safexcel_probe':
drivers/crypto/inside-secure/safexcel.c:1692: undefined reference to `devm_platform_ioremap_resource'
Fix the build error by adding the unspecified dependency.
