## Summary

Fixes #5256. Specify an initial baud rate to use during startup. After the PL011 code refactor in `0f421539598717a91cd7eee2b1cbf7ed32cb22f9`, an initial baud rate is required. `arm_pl011_first_open` is called from `boot_card` and will fail without a baud rate specified. This can cause certain future uses of `/dev/console`, such as opening a shell, to fail.
