All Armada 3720 boards have Armada 3720 processor which is of Armada 3700
family and do not have Armada 3710 processor. So none of them should have
compatible string for Armada 3710 processor.

Fix compatible string for all these boards by removing wrong processor
string "marvell,armada3710" and adding family string "marvell,armada3700"
as the last one. (Note that this is same way how are defined Armada 3710

riscv: switch to relative alternative entries
Instead of using absolute addresses for both the old instrucions and
the alternative instructions, use offsets relative to the alt_entry
values. So this not only cuts the size of the alternative entry, but
also meets the prerequisite for patching alternatives in the vDSO,
since absolute alternative entries are subject to dynamic relocation,
which is incompatible with the vDSO building.

riscv: introduce riscv_has_extension_[un]likely()
Generally, riscv ISA extensions are fixed for any specific hardware
platform, so a hart's features won't change after booting. This
chacteristic makes it straightforward to use a static branch to check
if a specific ISA extension is supported or not to optimize
performance.

However, some ISA extensions such as SVPBMT and ZICBOM are handled
via. the alternative sequences.

Basically, for ease of maintenance, we prefer to use static branches
in C code, but recently, Samuel found that the static branch usage in
cpu_relax() breaks building with CONFIG_CC_OPTIMIZE_FOR_SIZE[1]. As
Samuel pointed out, "Having a static branch in cpu_relax() is
problematic because that function is widely inlined, including in some
quite complex functions like in the VDSO. A quick measurement shows
this static branch is responsible by itself for around 40% of the jump
table."

Samuel's findings pointed out one of a few downsides of static branches
usage in C code to handle ISA extensions detected at boot time:
static branch's metadata in the __jump_table section, which is not
discarded after ISA extensions are finalized, wastes some space.

I want to try to solve the issue for all possible dynamic handling of
ISA extensions at boot time. Inspired by Mark[2], this patch introduces
riscv_has_extension_*() helpers, which work like static branches but
are patched using alternatives, thus the metadata can be freed after
patching.

Having a static branch in cpu_relax() is problematic because that
function is widely inlined, including in some quite complex functions
like in the VDSO. A quick measurement shows this static branch is
responsible by itself for around 40% of the jump table.

Drop the static branch, which ends up being the same number of
instructions anyway. If Zihintpause is supported, we trade the nop from
the static branch for a div. If Zihintpause is unsupported, we trade the
jump from the static branch for (what gets interpreted as) a nop.

dd25cfab16 Merge branch 'net-ipa-remaining-ipa-v5-0-support'
Alex Elder says:

====================
net: ipa: remaining IPA v5.0 support

This series includes almost all remaining IPA code changes required
to support IPA v5.0.  IPA register definitions and configuration
data for IPA v5.0 will be sent later (soon).  Note that the GSI
register definitions still require work.  GSI for IPA v5.0 supports
up to 256 (rather than 32) channels, and this changes the way GSI
register offsets are calculated.  A few GSI register fields also
change.

The first patch in this series increases the number of IPA endpoints
supported by the driver, from 32 to 36.  The next updates the width
of the destination field for the IP_PACKET_INIT immediate command so
it can represent up to 256 endpoints rather than just 32.  The next
adds a few definitions of some IPA registers and fields that are
first available in IPA v5.0.

The next two patches update the code that handles router and filter
table caches.  Previously these were referred to as "hashed" tables,
and the IPv4 and IPv6 tables are now combined into one "unified"
table.  The sixth and seventh patches add support for a new pulse
generator, which allows time periods to be specified with a wider
range of clock resolution.  And the last patch just defines two new
memory regions that were not previously used.

2cdbcbfd48 net: ipa: support a third pulse register
The AP has third pulse generator available starting with IPA v5.0.
Redefine ipa_qtime_val() to support that possibility.  Pass the IPA
pointer as an argument so the version can be determined.  And stop
using the sign of the returned tick count to indicate which of two
pulse generators to use.

Instead, have the caller provide the address of a variable that will
hold the selected pulse generator for the Qtime value.  And for
version 5.0, check whether the third pulse generator best represents
the time period.

Add code in ipa_qtime_config() to configure the fourth pulse
generator for IPA v5.0+; in that case configure both the third and
fourth pulse generators to use 10 msec granularity.

Consistently use "ticks" for local variables that represent a tick
count.

32079a4ab1 net: ipa: greater timer granularity options
Starting with IPA v5.0, the head-of-line blocking timer has more

To prepare for that, change the way the field value is encoded

The aggregation granularity selection could (in principle) also use
an additional pulse generator starting with IPA v5.0.  Encode the
AGGR_GRAN_SEL field differently to allow that as well.

IPA v5.0+ separates the configuration of entries in the cached
(previously "hashed") routing and filtering tables into distinct
registers.  Previously a single "filter and router" register updated
entries in both tables at once; now the routing and filter table
caches have separate registers that define their content.

This patch updates the code that zeroes entries in the cached filter
and router tables to support IPA versions including v5.0+.

8e7c89d84a net: ipa: update table cache flushing
Update the code that causes filter and router table caches to be
flushed so that it supports IPA versions 5.0+.  It adds a comment in
ipa_hardware_config_hashing() that explains that cacheing does not
need to be enabled, just as before, because it's enabled by default.
(For the record, the FILT_ROUT_CACHE_CFG register would have been
used if we wanted to explicitly enable these.)

8ba59716d1 net: ipa: define IPA v5.0+ registers
Define some new registers that appear starting with IPA v5.0, along
with enumerated types identifying their fields.  Code that uses
these will be added by upcoming patches.

Most of the new registers are related to filter and routing tables,
and in particular, their "hashed" variant.  These tables are better
described as "cached", where a hash value determines which entries
are cached.  From now on, naming related to this functionality will
use "cache" instead of "hash", and that is reflected in these new
register names.  Some registers for managing these caches and their
contents have changed as well.

A few other new field definitions for registers (unrelated to table
caches) are also defined.

c84ddc1197 net: ipa: extend endpoints in packet init command
The IP_PACKET_INIT immediate command defines the destination
endpoint to which a packet should be sent.  Prior to IPA v5.0, a
5 bit field in that command represents the endpoint, but starting
with IPA v5.0, the field is extended to 8 bits to support more than
32 endpoints.

07abde549b net: ipa: support more endpoints
Increase the number of endpoints supported by the driver to 36,
which IPA v5.0 supports.  This makes it impossible to check at build
time whether the supported number is too big to fit within the
(5-bit) PACKET_INIT destination endpoint field.  Instead, convert
the build time check to compare against what fits in 8 bits.

Add a check in ipa_endpoint_config() to also ensure the hardware
reports an endpoint count that's in the expected range.  Just
open-code 32 as the limit (the PACKET_INIT field mask is not
available where we'd want to use it).

Add fast update encryption key
 
 Jianbo Liu Says:
 ================
 
 Data encryption keys (DEKs) are the keys used for data encryption and
 decryption operations. Starting from version 22.33.0783, firmware is
 optimized to accelerate the update of user keys into DEK object in
 hardware. The support for bulk allocation and destruction of DEK
 objects is added, and the bulk allocated DEKs are uninitialized, as
 the bulk creation requires no input key. When offload
 encryption/decryption, user gets one object from a bulk, and updates
 key by a new "modify DEK" command. This command is the same as create
 DEK object, but requires no heavy context memory allocation in
 firmware, which consumes most cpu cycles of the create DEK command.
 
 DEKs are cached internally by the NIC, so invalidating internal NIC
 caches is required before reusing DEKs. The SYNC_CRYPTO command is
 added to support it. DEK object can be reused, the keys in it can be
 updated after this command is executed.
 
 This patchset enhances the key creation and destruction flow, to get
 use of this new feature. Any user, for example, ktls, ipsec and
 macsec, can use it to offload keys. But, only ktls uses it, as others
 don't need many keys, and caching two many DEKs in pool is wasteful.
 
 There are two new data struts added:
     a. DEK pool. One pool is created for each key type. The bulks by
 the type, are placed in the pool's different bulk lists, according to
 the number of available and in_used DEKs in the bulk.
     b. DEK bulk. All DEKs in one bulk allocation are store here. There
 are two bitmaps to indicate the state of each DEK.
 
 New APIs are then added. When user need a DEK object,
     a. Fetch one bulk with avail DEKs, from the partial_list or
 avail_list, otherwise create new one.
     b. Pick one DEK, and set its need_sync and in_used bits to 1.
 Move the bulk to full_list if no more available keys, or put it to
 partial_list if the bulk is newly created.
     c. Update DEK object's key with user key, by the "modify DEK"
 command.
     d. Return DEK struct to user, then it gets the object id and fills
 it into the offload commands.
 When user free a DEK,
     a. Set in_use bit to 0. If all need_sync bits are 1 and all in_use
 bits of this bulk are 0, move it to sync_list.
     b. If the number of DEKs, which are freed by users, is over the
 threshold (128), schedule a workqueue to do the sync process.
 
 For the sync process, the SYNC_CRYPTO command is executed first. Then,
 for each bulks in partial_list, full_list and sync_list, reset
 need_sync bits of the freed DEK objects. If all need_sync bits in one
 bulk are zero, move it to avail_list.
 
 We already supported TIS pool to recycle the TISes. With this series
 and TIS pool, TLS CPS performance is improved greatly.
 And we tested https on the system:
     CPU: dual AMD EPYC 7763 64-Core processors
     RAM: 512G
     DEV: ConnectX-6 DX, with FW ver 22.33.0838 and TLS_OPTIMISE=true
