e919b7ec20 sfxge(4): generalise EF10 NVRAM buffer interface
The SFN driver's PartitionControl WMI object requires an API to parse
and filter partition data in TLV format, particularly for the Dynamic
Config partition. The ef10_nvram_buffer functions provide this
functionality but are tied to use with license partition only.
Modify functions so they are applicable to all TLV partitions and add
functions to support in-place tag modification.

ede1a3edaa sfxge(4): precheck and verify flash writes
Read existing flash content before writing, so the flash write can be
avoided if the existing partition content matches the new image. This
avoids unnecessary write cycles for the flash device, and may also be
faster. If the flash does need to be updated, verify the content after
writing.

Note that reading the flash content after writing but before calling
efx_nvram-rw_finish() avoids firmware bug68170, which can lead to
signed image updates failing on Medford.

3d670ff531 sfxge(4): check NVRAM locking by partition ID

348d35299c sfxge(4): rename firmware update verify result cap field

As the capability only reports support for returning a verify
result, change the name to be less confusing.

718cf2ccb9 sys/dev: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

9ad7e03f72 sfxge: select whether to read current or backup partition in Medford A/B scheme
The dynamic config on Medford is stored using two partitions in flash, and at
any time one is the 'current' partition, used to provide the active config,
and the other 'backup' partition is used for writes.  This means that there
are two potential partitions that can be used to service reads, and which is
required can depend on, for example, whether the read is to get the current
contents or to verify a write.

When the partition write lock is held, the default behaviour is to read from
the backup partition, which was wrong for most reads in the common code which
require the current partition. This change allows the current partition to be
read whilst the write lock is held.
There is one read in Manftest which needs the backup partition.

ef10_nvram_partn_read_mode() is created to avoid changing
ef10_nvram_partn_read() which shares a prototype with the equivalent Falcon
and Siena methods.

MC_CMD_NVRAM_READ_IN_V2 adds an extra field, but firmware which doesn't support
it just ignores it.

460cb5684c sfxge: add prefast annotation to common code return types
Using a typedef for common code return types (rather than "int")
allows the Prefast static analyser to understand when a function
has been successful (and thus when its postconditions must hold).

This greatly reduces then number of false positives reported by
prefast for error paths in common code functions.
