* First batch of eeconfig conversions.

* Offset and length for datablocks.

* `via`, `dynamic_keymap`.

* Fix filename.

* Commentary.

* wilba leds

* more whack-a-mole

* `generic_features.mk` to automatically pick up nvm repositories

* thievery

* deferred variable resolve

* whitespace

* convert api to structs/unions

* convert api to structs/unions

* convert api to structs/unions

* fixups

* code-side docs

* code size fix

* rollback

* nvm_xxxxx_erase

* Updated location of eeconfig magic numbers so non-EEPROM nvm drivers can use them too.

* Fixup build.

* Fixup compilation error with encoders.

* Build fixes.

* Add `via_ci` keymap to onekey to exercise VIA bindings (and thus dynamic keymap et.al.), fixup compilation errors based on preprocessor+sizeof.

* Build failure rectification.

// The only reason this is important is in case EEPROM usage changes
