Description

https://github.com/oxidecomputer/quartz/pull/491 added a new register in the FMC-mapped FPGA that remembers which POST codes have been seen since boot in a "sticky" format, which is potentially a more compact thing to report in certain cases, for example in #2598, when a bootfail occurs.

Currently, we only support hubris draining the ring-buffer of POST codes, as implemented in: https://github.com/oxidecomputer/humility/pull/603.

This may also be relevant to https://github.com/oxidecomputer/hubris/issues/2097, depending on the details.
