To avoid missing arm64 specific warnings that get introduced
in this driver, allow compile-testing on all 64-bit architectures.
The only actual arm64 specific code in this driver is an open-
coded 128 bit MMIO write. On non-arm64 the same can be done
using memcpy_toio. What I also noticed is that the mmio store
(either one) is not endian-safe, this will only work on little-
endian configurations, so I also add a Kconfig dependency on
that, regardless of the architecture.
Finally, a depenndecy on CONFIG_64BIT is needed because of the
writeq().

This patch adds support for the EIP196, which is an EIP197 derivative
that has no classification hardware and a simplified record cache.
The patch has been tested with the eip196b-ie and eip197c-iewxkbc
configurations on the Xilinx VCU118 development board as well as on the
Macchiatobin board (Marvell A8K - EIP197b-ieswx), including the crypto
extra tests.
Note that this patchset applies on top of the earlier submitted
"Add support for eip197f_iewc" series.

The current driver assumes one dedicated ring interrupt controller per
ring. However, some existing EIP(1)97 HW has less ring AIC's than rings.
This patch allows the driver to work with such HW by detecting how many
ring AIC's are present and restricting the number of rings it *uses* by
the number of ring AIC's present. This allows it to at least function.
(optimization for the future: add ring dispatch functionality in the
interrupt service routine such that multiple rings can be supported from
one ring AIC, allowing all rings to be used)

This patch corrects an error in the Transform Record Cache initialization
code that was causing intermittent stability problems on the Macchiatobin
board.
Unfortunately, due to HW platform specifics, the problem could not happen
on the main development platform, being the VCU118 Xilinx development
board. And since it was a problem with hash table access, it was very
dependent on the actual physical context record DMA buffers being used,
i.e. with some (bad) luck it could seemingly work quit stable for a while.

Nowadays we have runtime PM, and we can use it with autosuspend_timeout
to idle things automatically. This allows us to get rid of the custom
PM implementation.
We enable clocks and init RNG in runtime_resume, and reset RNG and
disable clocks in runtime_suspend. And then omap3_rom_rng_read()
becomes very simple and we don't need the old functions for
omap3_rom_rng_idle() and omap3_rom_rng_get_random(). We can now also
get rid of pr_fmt as we're using dev_err instead.

When unloading omap3-rom-rng, we'll get the following:
WARNING: CPU: 0 PID: 100 at drivers/clk/clk.c:948 clk_core_disable
This is because the clock may be already disabled by omap3_rom_rng_idle().
Let's fix the issue by checking for rng_idle on exit.

Commit 0ed266d7ae5e ("clk: ti: omap3: cleanup unnecessary clock aliases")
removed old omap3 clock framework aliases but caused omap3-rom-rng to
stop working with clock not found error.
Based on discussions on the mailing list it was requested by Tero Kristo
that it would be best to fix this issue by probing omap3-rom-rng using
device tree to provide a proper clk property. The other option would be
to add back the missing clock alias, but that does not help moving things
forward with removing old legacy platform_data.
Let's also add a proper device tree binding and keep it together with
the fix.

In general we should check for GP device instead of HS device unless
the other options such as EMU are also checked. Otherwise omap3-rom-rng
won't probe on few of the old n900 macro boards still in service in

This patch adds support for the authenc(hmac(sha1),cbc(sm4)),

and authenc(hmac(sm3),rfc3686(ctr(sm4))) aead ciphersuites.
These are necessary to support IPsec according to the Chinese standard
GM/T 022-1014 - IPsec VPN specification.
Note that there are no testvectors present in testmgr for these
ciphersuites. However, considering all building blocks have already been
verified elsewhere, it is fair to assume the generic implementation to be
correct-by-construction.
The hardware implementation has been fuzzed against this generic
implementation by means of a locally modified testmgr. The intention is
to upstream these testmgr changes but this is pending other testmgr changes
being made by Eric Biggers.
The patch has been tested with the eip197c_iewxkbc configuration on the
Xilinx VCU118 development board, using the abovementioned modified testmgr

This patch adds support for the Chacha20-Poly1305 cipher suite.
It adds both the basic rfc7539(chacha20,poly1305) as well as the
rfc7539esp(chacha20,poly1305) variant for IPsec ESP acceleration.
changes since v1:
- rebased on top of DES library changes done on cryptodev/master
- fixed crypto/Kconfig so that generic fallback is compiled as well
changes since v2:
- nothing
changes since v3:
- Fixed a problem where the tcrypt performance test would run fully on the
fallback cipher instead of the HW due to using an AAD length of 8 for
rfc7539esp. While this is not actually legal ESP (which includes SPI and
sequence number in the AAD as well), it is both inconvenient and not
necessary to run these vectors on the fallback cipher.
- Due to above, also realised that for plain (non-ESP) rfc7539, you
probably want to be able to run vectors with less than 8 bytes of AAD
on the HW, and this is actually possible as long as cryptlen is large
enough, so made that possible as well.
