UEFI 2.7 defines in page 758 that: Initial Label Storage Area Configuration : The minimum size of the Label Storage Area is large enough to hold 2 index blocks and 2 labels. The mininum index block size is 256 bytes, and the minimum label size is also 256 bytes. Change ND_LABEL_MIN_SI

[PATCH 04/12] bus: ti-sysc: Improve handling for no-reset-on-init and no-idle-on-init

At least earlycon needs a delayed idle before the 8250 driver probes to avoid glitches in the console output.
