+Facebook Yosemite v3.5 Platform and CraterLake Server (``fby35``)
+==================================================================
+
+Facebook has a series of multi-node compute server designs named
+Yosemite. The most recent version released was
+`Yosemite v3 <https://www.opencompute.org/documents/ocp-yosemite-v3-platform-design-specification-1v16-pdf>`__.
+
+Yosemite v3.5 is an iteration on this design, and is very similar: there's a
+baseboard with a BMC, and 4 server slots. The new server board design termed
+"CraterLake" includes a Bridge IC (BIC), with room for expansion boards to
+include various compute accelerators (video, inferencing, etc). At the moment,
+only the first server slot's BIC is included.
+
+Yosemite v3.5 is itself a sled which fits into a 40U chassis, and 3 sleds
+can be fit into a chassis. See `here <https://www.opencompute.org/products/423/wiwynn-yosemite-v3-server>`__
+for an example.
+
+In this generation, the BMC is an AST2600 and each BIC is an AST1030. The BMC
+runs `OpenBMC <https://github.com/facebook/openbmc>`__, and the BIC runs
+`OpenBIC <https://github.com/facebook/openbic>`__.
+
+Firmware images can be retrieved from the Github releases or built from the
+source code, see the README's for instructions on that. This image uses the
+"fby35" machine recipe from OpenBMC, and the "yv35-cl" target from OpenBIC.
+Some reference images can also be found here:

+    $ wget https://github.com/peterdelevoryas/OpenBIC/releases/download/oby35-cl-2022.13.01/Y35BCL.elf
+
+Since this machine has multiple SoC's, each with their own serial console, the
+recommended way to run it is to allocate a pseudoterminal for each serial
+console and let the monitor use stdio. Also, starting in a paused state is
+useful because it allows you to attach to the pseudoterminals before the boot
+process starts.
