Based on https://github.com/sandeepmistry/arduino-nRF5/blob/master/cores/nRF5/SDK/components/toolchain/gcc/nrf52805_xxaa.ld

should this be:

0x30000 = 196608

Edit the macros in the compat header instead?
This is what I did here: edited cores/nRF5/SDK/components/device/nrf52_to_nrf52810.h and I didn't need to modify this file.

(See existing implementation for some other chips, see nrf52840 for example).

Should we be touching code in the SDK? Does that introduce potential upgrade complexity?

Good question for @sandeepmistry :)
It would be nice to have this consistency between compat .h files, like nrf52_to_nrf52840.h referenced above.

It would be better to avoid doing this, as it would be one more thing to manage when updating the SDK.

That said if it's the best approach wrapping changes in #ifdef ARDUINO would be best.

Am I good to leave this as-is for now? There is already series and, in some special cases, chip specific logic in the .cpp library files. I would prefer to leave this condition where it is until we decide on the best way/place to extend SDK definitions without modifying the SDK.

However, I'll do whatever you feel is best. There is increased interest to get this merged in, so whatever I can do to help expedite.
