The DMA stream will automatically disable itself as soon as the transfer
is finished. No need to do this an additional time after the transfer is
finished
This combines a number of register writes in the SPI
acquire and transfer code. The DMA enable for SPI is moved to the
acquire function, switching between DMA and regular transfer between
acquires is not possible.
Introduced 'GNRC_PKTDUMP_MSG_QUEUE_SIZE_EXP' to hold exponent
value and made GNRC_PKTDUMP_MSG_QUEUE_SIZE dependant on
GNRC_PKTDUMP_MSG_QUEUE_SIZE_EXP.
Moved 'GNRC_PKTDUMP_MSG_QUEUE_SIZE_EXP' to 'CONFIG_' namespace.
Exposed configurations to Kconfig

Before there were only two: "main" and "idle". But now there can also be
a thread for "usbus". The code will now use sched_num_threads and it
subtracts that number from MAXTHREADS.
This resolves issue #14180
The 6Lo network interfaces can only support a max_frag_size of
SIXLOWPAN_FRAG_MAX_LEN (2047 bytes) as the length field is only 11-bits.
This limits the max_frag_size in the case that the L2-PDU is higher than
that.

The STM32 line of microcontrollers comes with a bootloader in the ROM.
It provides the option to flash the device firmware in DFU mode (USB)
or via UART or SPI.
To enter the bootloader we have to jump to a specific address in memory,
but before reset the CPU to make sure the system is in a known state.
This enables us to use the usb_board_reset module on all STM32 platforms.
Modified to allow including sam0.inc.mk even if none of the programmers handled
their is used. This is useful for boards that by default are programmed via a
bootloader. Still including sam0.inc.mk allows users to specify the `PROGRAMMER`
to use jlink, openocd, or edgb instead of the bootloader.
This is an Arduino Zero clone without the embedded debugger. Thus, it will be
flashed by default using the U2F bootloader and uses by default USB CDC ACM for
STDIO.
