6d135d3579 native: make use of TLSF malloc and co
In order to make native behave more similar to other platforms, it should also use TLSF's dynamic memory allocation if included. It will still fall back to the system's malloc implementation when building for use with valgrind, to leverage its memory leak detection mechanisms.

f753ce7809 cpu/stm32f1: allow disabling spi peripherals
This allows disabling SPI peripherals even if defined in periph_conf.h
by setting the definition SPI_*_EN to 0.

The peripherals were tested against ifdef which caused to include the
code even if the peripheral was disabled, which was incompatible with
the current spi.h common implementation.

142c28094e kinetis_common: Refactor GPIO implementation
This is a rewrite of the Kinetis GPIO driver which follows the
refactored API in [1]. Pins are specified using the GPIO_PIN(PORT_x, y)
macro, e.g. GPIO_PIN(PORT_E, 25) for the PTE25 pin.

The interrupt pin handling is now implemented as a linked list, this
is more memory efficient, but with a minor variation in interrupt
latency depending on in what order the pins were initialized at
runtime.

Because the linked list entries are taken from a shared pool, there is
also the possibility of running out of available configuration slots,
define the preprocessor macro GPIO_INT_POOL_SIZE in periph_conf.h if
you need more than 16 pins configured for interrupts in the same
application.

c404bd97ad k60: Add workaround for errata e4218
e4218: SIM/FLEXBUS: SIM_SCGC7[FLEXBUS] bit should be cleared when the
FlexBus is not being used.

Errata type: Errata

Description:

The SIM_SCGC7[FLEXBUS] bit is set by default. This means that the
FlexBus will be enabled and come up in global chip select mode. With
some code sequence and register value combinations the core could
attempt to prefetch from the FlexBus even though it might not actually
use the value it prefetched. In the case where the FlexBus is
unconfigured, this can result in a hung bus cycle on the FlexBus.

Workaround:

 - If the FlexBus is not being used, disabled the clock to the FlexBus
   during chip initialization by clearing the SIM_SCGC7[FLEXBUS] bit.
 - If the FlexBus will be used, then enable at least one chip select as
   early in the chip initialization process as possible.
