Exceptional cases, that may still need early bus master enabling in the future, should get their own per-reason Kconfig option. Ideally before the next release. +### Early runtime configurability of the console log level + +Traditionally, we didn't allow the log level of the `romstage` console +to be changed at runtime (e.g. via `get_option()`). It turned out that +the technical constraints for this (no global variables in `romstage`) +vanished long ago, though. The new behaviour is to query `get_option()` +now from the second stage that uses the console on. In other words, if +the `bootblock` already enables the console, the `romstage` log level +can be changed via `get_option()`. Keeping the log level of the first +console static ensures that we can see console output even if there's +a bug in the more involved code to query options. + ### Add significant changes here Deprecations |
