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.

0ca2ce0214 cpu/esp32: unconditionally disable thin archives 
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.

7e5aa7e775 cpu/sam0_common: uart: fix baud rate calculation 
In fractional mode, 3 bits are used to store the fractional part.
Therefore we must multiply / divide by 8 instead of 10 in order to
get the correct values.

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.

111fe80eb9 cpu/esp: disable thin archives if esp_wifi is used 
For a yet unknown reason, both esp8266 and esp32 get stuck in a
reboot loop when thin archives are used.

As a workaround, disable thin archives for now if esp_wifi is used.

* CPU files should already have 'CPU' defined by the board.
* Do not conditionally define CPU as it is not needed.

Makefile.features.
