This patch derives the result descriptor fetch count from the actual
FIFO size advertised by the hardware. Fetching result descriptors
one at a time is a performance bottleneck for small blocks, especially
on hardware with multiple pipes. Even moreso if the HW has few rings.

This patch adds automatic EIP97/EIP197 detection, so it does not need to
rely on any static value from the device table anymore. In particular,
the static value from the table won't work for PCI devboards that cannot
be further identified save from this direct hardware probing.
The patch also adds automatic host xs endianness detection & correction.

This patch probes the supported algorithms from the hardware and only
registers the ones that the hardware actually supports. This is necessary
because this is a generic driver supposed to run on a wide variety of
engines, which may or may not implement certain algorithms.

Until now, the inside-secure driver required a set of firmware images
supplied by the silicon vendor, typically under NDA, to be present in
/lib/firmware/inside-secure in order to be able to function.
This patch removes the dependence on this official vendor firmware by
falling back to generic "mini" FW - developed specifically for this
driver - that can be provided under GPL 2.0 through linux-firmwares.

This removes some code determine which engine has which algorithms which
was effectively redundant (may have been forward-looking?) due to always
enabling all algorithms for all currently supported engines.
A future patch will use a different, more scalable approach to achieve
this. This is removed now because otherwise the next patch will add new
hardware which would otherwise have to be added to all algorithms, so
now is a convenient time to just get rid of this.

As done treewide earlier, this catches several more open-coded
allocation size calculations that were added to the kernel during the
merge window. This performs the following mechanical transformations
using Coccinelle:
kvmalloc(a * b, ...) -> kvmalloc_array(a, b, ...)
kvzalloc(a * b, ...) -> kvcalloc(a, b, ...)
devm_kzalloc(..., a * b, ...) -> devm_kcalloc(..., a, b, ...)

This patch main goal is to improve driver performance by moving the
crypto request from a list to a RDR ring shadow.
This is possible since there is one producer and one consume for this
RDR request shadow and one ring descriptor is left unused.
Doing this change eliminates the use of spinlock when accessing the
descriptor ring and the need to dynamicaly allocate memory per crypto
request.
The crypto request is placed in the first RDR shadow descriptor only
if there are enough descriptors, when the result handler is invoked,
it fetches the first result descriptor from RDR shadow.

The ORO bridge (connected to the EIP197 write channel) does not
generate back pressure towards the EIP197 when its internal FIFO is
full. It assumes that the EIP will not drive more write transactions
than the maximal supported outstanding (32).
Hence tx_max_cmd_queue must be configured to 5 (or less).

Add a flags field in the private structure, and a first flag for engines
needing context invalidation (currently only the eip197b). The
invalidation is needed when the engine includes a TRC cache, which will
also be true for the upcoming addition of the eip197d engine.

EIP engines do not support the same set of algorithms. So far the

are registered when using a compatible cryptographic engine.

At first we used two compatibles in the SafeXcel driver, named after the
engine revision: eip97 and eip197. However this family of engines has
more precise versions and in fact we're supporting the eip97ies and
eip197b. More versions will be supported in the future, such as the
eip197d, and we'll need to differentiate them.
This patch fixes the compatibles used in the driver, to now use precise
ones. The two historical compatibles are kept for backward
compatibility.

This patch moves the firmware loaded by the Inside Secure SafeXcel
driver from /lib/firmware/ to /lib/firmware/inside-secure/eip197b/. This
prepares the driver for future patches which will support other
revisions of the EIP197 crypto engine as they'll have their own
firmwares.
To keep the compatibility of what was done, the old path is still
supported as a fallback for the EIP197b (currently the only one
supported by the driver that loads a firmware).
