Rename the variable to make it clearer that it refers to the last Makefile
included.
Usually this is the current file, but when another Makefile is included this
changes.
- _rom_start_addr, _ram_start_addr, _rom_length and _ran_length are
already defined in cortexm_common/Makefile.included and can therefore
be removed from kinetis/Makefile.include
- _ram_base_addr is never used and was not in commit history so
is also removed
Rational: the periph_common module is required by (most) other periph drivers
and also during startup of the CPU/MCU to run periph_init. The latter is only
required if other periph drivers are used, hence periph_common should be a
depency of periph_* modules and *not* of the CPU/MCU. This PR fixes that
by making periph_common a depency of periph_* and removing the explicit
include in the CPU/MCU implementation.
Keep the compiled '.bin' file to remove the need to compile it when
flashing. This remove the need to have the toolchain when flashing so
allow compiling and flashing with `BUILD_IN_DOCKER=1` without a local
toolchain.
Even if it ends up storing a binary, the file is only 34 bytes.
It must be evaluated in `cortexm_common` without a shell context.
The `K` is correctly handled by both the linker and `cortexm_common`.
