This is a port of the corresponding commit in the Linux kernel which
adds the same support for the Cadence Torrent driver[0]. The commit
message below is taken as-is from the Linux kernel commit being ported.
The Torrent SERDES can support at most two different protocols (PHY types).
This only mandates that the device-tree sub-nodes used to represent the
configuration should describe links with at-most two different protocols.
The existing implementation however imposes an artificial constraint that
allows only two links (device-tree sub-nodes). As long as at-most two
protocols are chosen, using more than two links to describe them in an
alternating configuration is still a valid configuration of the Torrent
SERDES.
A 3-Link 2-Protocol configuration of the 4-Lane SERDES can be:
Lane 0 => Protocol 1 => Link 1
Lane 1 => Protocol 1 => Link 1
Lane 2 => Protocol 2 => Link 2

Background:
I have several customers that will be using a certain remote signing
service for signing their images, in order that the private keys are
never exposed outside that company's secure servers. This is done via
a pkcs#11 interface that talks to the remote signing server, and all
of that works quite well.
However, the way this particular signing service works is that one
must upfront create a "signing session", where one indicates which
keys one will use and, importantly, how many times each key will (may)
be used. Then, depending on the keys requested and the customer's
configuration, one or more humans must authorize that signing session
So for example, if official release keys are to be used, maybe two
different people from upper management must authorize, while if
development keys are requested, the developer himself can authorize
the session.
Once authorized, the requester receives a token that must then be used
for signing via one of the keys associated to that session.
I have that integrated in Yocto in a way that when a CI starts a BSP
build, it automatically works out which keys will be needed (e.g. one
for signing U-Boot, another for signing a kernel FIT image) based on
bitbake metadata, requests an appropriate signing session, and the
appropriate people are then notified and can then look at the details
of that CI pipeline and confirm that it is legitimate.
The problem:
The way mkimage does FIT image signing means that the remote server
can be asked to perform a signature an unbounded number of times, or
at least a number of times that cannot be determined upfront. This
means that currently, I need to artificially say that a kernel key
will be used, say, 10 times, even when only a single FIT image with
just one configuration node is created.
Part of the security model is that once the number of signings using a
given key has been depleted, the authorization token becomes useless
even if somehow leaked from the CI - and _if_ it is leaked/compromised
and abused before the CI has gotten around to do its signings, the
build will then fail with a clear indication of the
compromise. Clearly, having to specify a "high enough" expected use
count is counter to that part of the security model, because it will
inevitably leave some allowed uses behind.
While not perfect, we can give a reasonable estimate of an upper bound
on the necessary extra size by simply counting the number of hash and
signature nodes in the FIT image.
As indicated in the comments, one could probably make it even more
precise, and if there would ever be signatures larger than 512 bytes,
probably one would have to do that. But this works well enough in
practice for now, and is in fact an improvement in the normal case:
Currently, starting with size_inc of 0 is guaranteed to fail, so we
always enter the loop at least twice, even when not doing any signing
but merely filling hash values.
Just in case I've missed anything, keep the loop incrementing 1024
bytes at a time, and also, in case the estimate turns out to be over
64K, ensure that we do at least one attempt by changing to a do-while
loop.
With a little debug printf, creating a FIT image with three
configuration nodes previously resulted in
Trying size_inc=0
Trying size_inc=1024
Trying size_inc=2048
Trying size_inc=3072
Succeeded at size_inc=3072
and dumping info from the signing session (where I've artifically
asked for 10 uses of the kernel key) shows
"keyid": "kernel-dev-20250218",
"usagecount": 9,
"maxusagecount": 10
corresponding to 1+2+3+3 signatures requested (so while the loop count
is roughly linear in the number of config nodes, the number of
signings is quadratic).
With this, I instead get
Trying size_inc=3456
Succeeded at size_inc=3456
and the expected
"keyid": "kernel-dev-20250218",
"usagecount": 3,
"maxusagecount": 10
thus allowing me to set maxusagecount correctly.
Update a binman test case accordingly: With the previous behaviour,
mkimage would try size_inc=0 and then size_inc=1024 and then
succeed. With this patch, we first try, and succeed, with 4*128=512
due to the four hash nodes (and no signature nodes) in 161_fit.dts, so
the image ends up 512 bytes smaller.

This series solves a contradiction regarding ext blobs packaged in
binman. When they are marked as optional, by default they are faked, two
messages are emitted. One says the image is not functional the other
says the image is still functional. Both concern the same binman
entry/blob.
Binman is set up to have fake external blobs in case they are missing.
This is regardless on whether they are optional or not.
The implementation does not allow different types of entries to override
the faking decision; at least there wouldn't be much sense in doing so.
Here is an example build output of a phycore-imx8mp:
BINMAN .binman_stamp
Image 'image' is missing optional external blobs but is still functional: tee-os

When blobs are absent and are marked as optional, they can be safely
dropped from the binman tree. Use the drop_absent function for that.
Rename drop_absent to drop_absent_optional as we do not want to drop any
entries that are absent; they should be reported by binman as errors
when they are missing.
We also reorder the processing of the image the following:
- We call the CheckForProblems function before the image is built.
- We drop entries after we checked for problems with the image.
This is okay because CheckForProblems does not look at the file we have
written but rather queries the data structure (image) built with binman.
This also allows us to get all error and warning messages that we want
to report while avoiding putting missing optional entries in the final
image.
As only the blobs are dropped, the sections still remain in the
assembled image. Thus add them to the expected test case checks where
necessary.
In addition, a rework of testPackTeeOsOptional test case is necessary.
The test did not really do what it was supposed to. The description said
that optional binary is tested, but the binary is not marked as
optional. Further, the tee.elf file, when included in the image
properly, also shows up in the image data. This must be added as well.
As there is no global variable for the elf data, set the pathname to the
elf file that was created when setting up the test suite.
For the test case get the filename and read the contents, comparing them
to the contents of the created binman image.

Optional blobs should mark themselves as absent to avoid being packed
into an image.
Extend the documentation of this behaviour. Although the documentation
implied this before, the "optional" property had not been explained
properly before.
The behaviour will change as now absent entries are no longer
packed into an image. The image map will also reflect this.
As a result, the CheckForProblems() function will no longer alert on
optional (blob) entries. This is because the missing optional images
were removed before CheckForProblems is called.
Adjust the testExtblobOptional test case to highlight that we are
testing not only an optional image but the image is missing as well. The
behaviour for these is different where the latter will not be packaged
into the image.
