fallback v0.9.6 for 7z014s

This release includes the EEPROM Fault Log feature in the fallback
image. This feature records significant IPMI or fault related events.
While there are no sensors or events to log in fallback, the ability to
read out this log from a fallback mode, even without SDR information,
can be valuable.

fallback v0.9.6 for 7z020

This release includes the EEPROM Fault Log feature in the fallback
image. This feature records significant IPMI or fault related events.
While there are no sensors or events to log in fallback, the ability to
read out this log from a fallback mode, even without SDR information,
can be valuable.

CDB v1.0.4 for 7z020

This release integrates various fixes related to the initialization of
the EEPROM boottarget field on fresh cards, as well as the
`image_tag_lock` command.

fallback v0.9.5 for 7z014s

This release fixes a bug in the firmware update procedure where the
Image Tag Lock feature would automatically be enabled when uploading a
firmware image tagged e.g. "fallback-7z014s" to the primary partition,
because it did not match "fallback".  This will no longer occur.  The
current image tag lock setting can be manipulated with the
`image_tag_lock` command.

This issue affects only fallback images applied to the primary
(operational) partition.  It is considered a low priority update on RevB
IPMCs.

The help text for the `image_tag_lock` command has also been improved.

fallback v0.9.4 for 7z014s

This release fixes a bug with the handling of the boot target field in
uninitialized EEPROM (such as on fresh boards).

fallback v0.9.4 for 7z020

This release fixes a bug with the handling of the boot target field in
uninitialized EEPROM (such as on fresh boards).

fallback v0.9.3 for 7z014s

This release restores some IO testing routines and functionality that
were lost in prior refactors.

fallback v0.9.3 for 7z020

This release restores some IO testing routines and functionality that
were lost in prior refactors.

CDB v1.0.3

This update blocks firmware updates when the card is not in an M1 state,
and will not allow the card to leave M1 until the IPMC has been
restarted if an update is applied.

fallback v0.9.2 for 7z014s

This release includes significant upgrades to the image management and
verification facilities of the IPMC.

The "A" and "B" partitions have been replaced with "primary" and "backup"
partitions containing the most recent, and second most recent image
applied.  This design prevents confusion with regard to whether A or B
is current, and allows updates to be done in a uniform manner without
assuming (possibly incorrectly) the partition configuration of the card.

Updates automatically program the next image slot, and boottarget can be
used to undo an update.

In addition to this change, images are now validated by reading the ZYNQ
part out of the bitstream, as well as the ZYNQ device ID register to
ensure that an IPMC based on a 7z020 part will not accept e.g. a 7z014s
based image.

Images are now also validated by confirming that the git tag in the
embedded version information matches the expected git tag, if
configured, to limit exposure to instances of confusion where an IPMC
running on one type of carrier board is programmed with an image for a
different type of carrier board which is not electrically safe for it.

Images are also validated when switching boot target as well as at
upload time, so it is not possible to accidentally select an
unprogrammed or invalid boot target.

This release also includes a 2 second delay in early boot, for power-on
resets only, to allow for JTAG recovery of boot loops.
