cpu/sam0_common: derive ROM_LEN, RAM_LEN from part number & vendor file
...
The ROM size is encoded in the part number of the Atmel SAM chips.
RAM size is not encoded directly, so get it by parsing the chip's vendor file.
The file remains in the page cache for the compiler to use, so the overhead
should be minimal:

cpu/esp_common: stop WiFi interface before sleep/reboot
...
The WiFi interface should be stopped before reboot or sleep. But stopping the WiFi interface disconnects an existing connection. Usually, esp_wifi_netdev tries to reconnect on an disconnect event. However, trying reconnect with a stopped WiFi interface may lead to a crash. Therefore, the stop event has to be handled.

Those IRQs aren't used on cc26x0 radio so it shouldn't affect anything.

Make sure the mpu_noexec_ram regions has the lowest priority
...
From the ARMv7-M ARM section B3.5.3:
Where there is an overlap between two regions, the register with
the highest region number takes priority.
We want to make sure the mpu_noexec_ram region has the lowest
priority to allow the mpu_stack_guard region to overwrite the first N
bytes of it.
This change fixes using mpu_noexec_ram and mpu_stack_guard together.

In the lightest mode (3) any interrupt source can wake up the CPU.
In mode 2, only RTT, GPIO or USB may wake the CPU.
In mode 1 only RTT and GPIO can wake the CPU.
In mode 0 only GPIO can wake the CPU.
In mode 0 and 1 the lower 16k RAM are lost. This is a problem since those
are usually used by RIOT.
The linkerscripts in cc2538/ldscripts take different approaches towards that.
Some only use the upper 16k and leave the other half to be managed by the
application.
`cc2538sf53.ld` which is used by `openmote-b` uses the entire RAM starting
at the lower half, so it will not be able to wake up from those modes.
A quick fix to test those modes with `tests/periph_pm` would be

We have to read the DR for every byte that we write.
Just reading DR while SPI is busy in a loop can lead to bytes being

nrf5x: Add built-in DC/DC converter enable function

The internal DC/DC converter is more efficient compared to the LDO
regulator. The downside of the DC/DC converter is that it requires an
external inductor to be present on the board. Enabling the DC/DC
converter is guarded with NRF5X_ENABLE_DCDC, this macro must be defined
if the DC/DC converter is to be enabled.

cpu/atmega_common: Implement RTC based on TIM2
...
This implements a basic Real Time Clock based on TIM2.
As the timer is too fast and wraps around after just 8 bits, it is
not used directly. Instead TIM2 is responsible for providing a 1 Hz
tick by generating an alarm every second.
The current time data is kept in the `.noinit` section, so it will survive
a reboot, but the clock will not be updated while the bootloader runs, so
expect inaccuracies.

The split between GEN2_ULP32K and GEN3_ULP32K was introduced to fix

By not running the external oscillator on demand, the failure can no
