We're seeing warnings about `Inconsistent data wrt SRAM type` in the [simulator log](https://buildomat.eng.oxide.computer/wg/0/artefact/01JSEQ3S3PGETF56NBK1GHMZTF/yeSvekn2FMH3DgWHCh47dMzHcUFQWq8IwTHKBkWd4gwPy6Sf/01JSEQ45FYXVNHDEABD627E471/01JSEQKC0F1Z0ZT6ECVENDQ1P5/simulator.log?format=x-bunyan#L99). We need to explore this, as it came about when doing PRE in https://github.com/oxidecomputer/dendrite/pull/14.
