Such that they are easier to adapt. The maximum code size is set by:
MICROPY_HW_CODESIZE=xxxK
in mpconfigmcu.mk for the MCU family as default or in mpconfigboard.mk for
a specific board. Setting the maximum code size allows the loader to error
out if the code gets larger than the space dedicated for it.
