01b3484ffb cpu/saml21: add definitions for low power SRAM 
SAML21 provides 2/4/8 kiB of Low Power SRAM that is retained
in backup mode.

This adds definitions to make that memory availiable to RIOT.

2c09d9bd5b cpu/cortexm_common: Make Low-Power SRAM available to programs 
Many MCUs contain some Backup or Low Power SRAM that is retained'even
in the deepest sleep modes.

In such sleep modes the MCU is essentually turned off with only the RTC
still running.
It can be woken by a GPIO or a RTC alarm. When this happens, a reset is
triggered and the normal startup routine is invoked.

This adds bss & data section for this memory in the linker script.
This allows for structures to be placed in it e.g.:

e.g.:

    static uint8_t persistent_buffer[64] __attribute__((section(".backup.bss")));
    static uint32_t persistent_counter __attribute__((section(".backup.data"))) = 1234;

c9b827e5d5 sam0_common: export flag that tells if the CPU woke from deep sleep 
It is often useful to know whether the CPU was just powered on afresh
or if it was woken from a deep sleep state, e.g. by RTC or GPIO event.

Thin archives also cause a boot loop when using the flash module.
To prevent further surprises, disable thin archives unconditionally
until the cause for this behaviour is known.

736e5e5a35 cpu/samd5x: allow more flexible selection of CLOCK_CORECLOCK 
There are some constraints to the oscillators on the samd5x.

 - DFLL is fixed to run at 48 MHz
 - DPLL can run at 96 to 200 MHz

Always use DFLL for frequencies <= 48 MHz.
For frequencies >= 96 MHz, use DPLL directly.
For frequencies < 96 MHz, clock DPLL at twice the desired frequency
and use a divider.

b415588677 cpu/mips32r2: remove nomips16 attribute from _mips_handle_exception 
A note says "The nomips16 attribute should not really be needed,
it works around a toolchain issue in 2016.05-03."

In fact, in 2018.09-03, the attribute leads to this error:

```cpu/mips32r2_common/thread_arch.c:191:1: error: ‘_mips_handle_exception’ redeclared with conflicting ‘nomips16’ attributes```

This this commit removes the attribute.

This reverts commit 422644bd3a.

The option is only supported after 2.6 which is currently not the
version given with 'esp' toolchain.
It was a bit too early to switch to the new version.
Version 2.7 also supports the old option with only a warning.

b1724a7d1b periph/rtc: normalize struct tm before usage 
A naive implementation may set a RTC alarm in 30s by calling

	struct tm now;
	rtc_get_time(&now);
	now.tm_sec += 30;
	rtc_set_alarm(&now, _cb, NULL);

This works for RTC implementations that use a RTT internally and call
mktime() to convert the struct tm to a unix timestamp, as mktime() will
normalize the struct in the process.

Call rtc_tm_normalize() when the RTC uses separate registers for time / date
components to ensure it is normalized.

This also modifies tests/periph_rtc to exercise this case.

f7279c84bb cpu/sam0_common: rtt: correcly clear flags. 
The INTFLAGS register is cleared by writing a 1 to the corresponding interrupt
flag bit. From the samr21's manual:

> Writing a zero to this bit has no effect.
> Writing a one to this bit clears the Compare 0 interrupt flag.

This is a common pattern in flag registers.

This RTT driver is using or-equal to clear the flags, which means it can
possibly clear other interrupts. There's a small chance that one event is
missed if it happens very close to another event.

Credits to @benpicco, @dylad for pointing out missing fixes.
