4f977316fe 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.

345827ce7b cpu/cc2538: gpio: save a few cycles in handle_isr() 
If only one it is set in state (one GPIO pin caused an interrupt),
don't loop over all 8 bits.

Use clz to get the position of the first interrupt bit and clear it,
looping only as many times as there are actual interrupts.

`rtc_init` is used after light sleep to update the system time from RTC timer. The fix corrects a small difference of about 230 ms which would sum up with each wakeup from light sleep.

cc26xx_cc13xx: add RFC_DBELL/RFC_PWR definitions 
This definition is compatible with `cc26x0` and `cc26x2_cc13x2`.

The only difference is (cc26x0 -> cc26x2_cc13x2):

- IRQ13 -> FG_COMMAND_STARTED
- IRQ12 -> COMMAND_STARTED

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

59676a1f5e 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.

5d8c00e302 cpu/cc2538: implement periph/pm 
cc2538 implements 4 sleep modes.
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

68b2c57d2d cpu/cc2538: spi: fix spi_transfer_bytes() with in_buf = NULL 
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
left in the fifo, corrupting subsequent reads.

cpu/{stm32r1,stm32_common}: Allow exposing JTAG pins as GPIOs 
- cpu/stm32f1: Removed previous code in gpio_init() to provide PB4 on the
  Nucleo-F103RB only
- cpu/stm32_common: Introduced STM32F1_DISABLE_JTAG which, if defined in
  board.h, exposes the JTAG only pins as GPIOs. This keeps the SWD pins, so that
  SWD debugging remains possible

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.

93d2068a9e 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.

fd9a247200 cpu/sam0_common: use generic exti_config 
Creating an `exti_config` array for a new MCU manually is tedious and error prone.
Luckiely all information is already availiable in the vendor files.

Credit for this discovery & method goes to @Sizurka

The file was generated with

```C

int main(void) {
        puts("static const int8_t exti_config[PORT_GROUPS][32] = {");

        for (unsigned port = 1; port < 5; ++port) {
                printf("#if PORT_GROUPS >= %d\n{\n", port);
                for (unsigned pin = 0; pin < 32; ++pin) {
                        printf("#ifdef PIN_P%c%02uA_EIC_EXTINT_NUM\n", '@' + port, pin);
                        printf("    PIN_P%c%02uA_EIC_EXTINT_NUM,\n", '@' + port, pin);
                        printf("#else\n    -1,\n#endif\n");
                }
                printf("},\n#endif\n\n");
        }

        puts("};");

        return 0;
}
```

No changes in generated code are expected, but this makes adding new members
of the sam0 CPU families much easier.

9f4920329b cpu/lpc2387: clear BODR if POR is set 
From the data sheet:

> **Note:** Only in case when a reset occurs and the POR = 0, the BODR bit
indicates if the V DD(DCDC)(3V3) voltage was below 2.6 V or not.

So the value of BODR is undefined if POR is set.
Clear it to bring it to a defined state.

76e19602a2 cpu/lpc2387: rename cpu_woke_from_backup() 
The function would always return `true` after early boot, so it
is not very useful for applications.

Now it will only (but always) return true when we woke from Deep Sleep
*after* early boot. This makes it behave the same ways as the function
of the same name on SAME54.

Rename the existing function to cpu_backup_ram_is_initialized() to better
match it's semantics.

64107dd3a9 cpu/lpc2387: rtc: only initialize RTC after cold boot or external reset 
On the MCB2388 plugging the power will result in both the POR and EXTR
bit being set.
Not sure if this is a property of the board, but it means RTC is also
reset after programming, so it behaves just like Backup RAM.

If we woke from Deep Sleep the POR bit will be cleared, so the RTC is not
reset.

80dde82c86 cpu/lpc2387: clear POR bit if we woke from Deep Sleep 
RSIR is 0x1 (POR) if we woke from Deep Sleep.
This makes it hard to distinguish between real power-on and waking from
Deep Sleep, which is why the Backup RAM signature was introduced.

However, calling cpu_woke_from_backup() a second time will always return
true, as the signature will have been set up by early boot then.

Thus, clear the POR bit if the signature was already in place.
The result is:

	RSIR == 0 -> woke from sleep
	RSIR == 1 -> cold boot

cpu/atmega_common: Fix pm_reboot with LTO 
The reboot process for ATmegas is to enable the watchdog timer and loop until
the wdt reboots this MCU. However, this reboot will keep the wdt configuration,
so that the wdt needs to be disabled during boot. This is done in get_mcusr,
but without the attribute "used" it will be optimized out in LTO builds. This
commits adds the attribute "used" to get_mcusr.

Also simplified the backward compatibility with older ATmegas (currently not
supported by RIOT) on outdated versions of avrlibc.
