I'm wondering if all Aurix processors feature overlay RAM for e.g. calibration, or if this is only available in certain variants like ED versions.

Hi ThePeter,

If you check RABRi(i=0-31) register, you could found the OMEM field:

Overlay Memory Select:

0-5H: Core0-5 DSPR/PSPR memory

8H: LMU

9H: EMEM

AH: EBU

...

For EMEM,  please check TC3xx ED device datasheet, and please note that i.e. TC399XX has 4096KB EMEM too, please check TC39x variants pdf if need.
