boards/samd21-arduino-bootloader: add common board module This module implements the 2 functions called when requesting a board 'reset in application' and 'board reset in bootloader' actions. This module will also configure the behaviour of bossa flasher and has a dependency on USBUS CDC ACM module for providing STDIO over USB 2019-09-30 17:16:00 +02:00			`# setup the flash tool used`

boards/samd21-arduino-bootloader: increase preflash delay The USB bootloader can take a while to be ready / Linux takes a while to set up the interface. 1s is right at the edge, leading to races and often failed flashing. Bump the delay to 2s for a wider safety margin, with this flashing is a lot more reliable. 2021-02-09 16:13:23 +01:00			`PREFLASH_DELAY ?= 2`
