CPU_HAS_SRAM_BITBAND can be used to check whether bit-banding is supported for
all of SRAM. With partially supported bit-banding, this feature is more of a
foot gun that a valuable tool.
MCG_Lite is used in many KL parts and is a less advanced clock generator
than the full MCG used in the K series. This change lets the MCG_Lite
and MCG share the same user facing API, with some configuration
differences.
Use RTC helper functions instead of libc functions.
This gives us y2038 safety by the extended epoch
and saves a good chunk of memory:

The spi scalar calculation tool for the kinetis family is stand-alone
and doesn't use the RIOT headers. It doesn't include the ARRAY_SIZE
macro from the RIOT headers. This commit adds a local definition of the
ARRAY_SIZE macro
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.
This moves the following modules to a architecture-specific Makefile.dep
file:
- cortexm_common
- cortexm_common_periph
- newlib
- newlib_nano
- periph
Now that CPU and CPU_MODEL are defined in the board's Makefile.features
it can be used to determine the available features provided by the
specific model.
- Removed stdio_init() from newlib's _init(), as this is too late in the boot
process to allow DEBUG()ing during periph_init()
- Added stdio_init() to the various cpu_init() routines of the ARM CPUs just
before periph_init()
On cppcheck 1.82 it throws a warning.
Since it costs cycles and does nothing the ++dummy is (void)dummy.
A warning suppression is added so the CI is happy.
This fixes the positive result when master write data is NACKed.
This false positive occurs when the write frame is finished but a data nack occurred.
The AF check should occur first.
