How much memory to reserve for bootloader program code.
If you are using bootloader in your application, specify
max size of bootloader partition. This memory will be
reserved at the beginning of flash, and CPU1 progmem will
be right after bootloader.
If you don't use bootloader and just want to run program
directly after reset, set this to 0.
