can't be adding bool to these symbols, will have to do a workaround similar to:

config BOARD_HAS_W25Q080
	bool
	default y if BOARD_RP2040_PLUS || BOARD_RP2040_PLUS_16MB
	select RP2_FLASH_W25Q080

though this still doesn't make sense as the w25q080 is an 8Mbit part?

I don't think I can do a multi-line suggestion, but I think the more Zephyr-y way of doing this would be to define multiple boards here. Like this:

boards:
  - name: rp2040_plus
    full_name: RP2040-Plus
    vendor: waveshare
    socs:
    - name: rp2040

  - name: rp2040_plus_16m
    full_name: RP2040-Plus-16MB
    vendor: waveshare
    socs:
    - name: rp2040

This would mean the full_name in Zephyr == Part Number at https://www.waveshare.com/rp2040-plus.htm?sku=23503 and https://www.waveshare.com/rp2040-plus.htm?sku=20290
