We will reserve BOARD_FLASH_SIZE for the internal flash on stm32 flash processors, use HAL_PROGRAM_SIZE_LIMIT_KB in the general code base.
Notable change here is that boards with external flash will start to get features only available with more than 2MB of program storage
This fix probably reflects the original intention of the code author, because without it delays set in detect_servos() are ignored.
Without this fix Dynamixel XC330-T288-T does not start and enters something like a "soft bricked" state (no errors reported, but not responding to any commands). This adds a delay after ping messages so that servos have time to respond to the pings and are ready to be configured further.
