af0718dc3a spi: add Kconfig entries for SPI4 and SPI5.
The SAM0 series has up to 6 SPI ports.  Add Kconfig options to match.

Similar to the 9033fb2f01, this patch
only defines the fields that are currently used and skips ones like
GPIO and IRQ priority that aren't.

Implement write-attribute on obj/obj_inst/res according to LwM2M spec
20170704-A, sec 5.1.2. Support pmin/pmax/st/gt/lt parameters on WRITE

The basic idea is to add sys_slist_t to obj/obj_inst/res structure.
And attach struct lwm2m_attr to the list when attributes are written
from server side (implement lwm2m_write_attr_handler accordingly)

Instead of wildcards we now are using environment variables to set the

Also, when something like this happens in the future, we should abort on

4b61bd1b7a kconfig: Prune kconfig files that don't match the ARCH or BOARD
When Kconfiglib was introduced it caused a significant performance
issue. This patch uses pruning to mitigate the performance issue.

The pruning exploits the fact that before the Kconfig database is
parsed we already know what ARCH and BOARD has been selected. So in
theory we could prune away all Kconfig sources that are not related to
the current ARCH or BOARD. In practice, it is only the Kconfig sources
in zephyr/arch/$ARCH and zephyr/board/$ARCH/ that are easy to prune.

Still, that is quite a few Kconfig sources. For qemu_x86 this patch
reduced the number of parsed Kconfig source files from 632 to
272. This pruning resulted in a incremental reconfiguration (time
cmake ..) speedup of 21% (0.56s to 0.46) and a clean build speedup of
4% (Using board qemu_x86 and sample hello_world).

Furthermore, it should be easier to maintain ARCH's and BOARD's
out-of-tree since the user now has a mechanism to redirect where
Kconfig sources are found. But this has not been explored.

a8b361b176 cmake: kconfig: Run Kconfig on every reconfiguration
Kconfiglib does not support merging fragments without parsing the
entire Kconfig "database". For Zephyr this means we no longer get a
performance gain from splitting up the fragment-merging and the
.config generation.

This patch removes the seperated merge step and it's associated
caching mechanism. Now we do a full Kconfig execution on every
reconfiguration.

We have been using a fork of the Linux kernel's Kconfig system to
configure the Zephyr tree. The issue is that this is a native tool
written in C that is not easy to compile for Windows. This patch

uses Kconfiglib to generate the .config and autoconf.h files required to
compile Zephyr.

59f0c99f0e spi: stm32: Correctly apply CPOL and CPHA settings
SPI_MODE_GET() returns a bitfield. It is thus wrong to test if a bit is
set using the equality operator. The bit-wise AND operator must be used
instead.

This can be tested by setting the SPI in mode 3 (CPOL + CPHA). Currently
both tests will fail and the result is a SPI configured in mode 0. This
was confirmed using an oscilloscope. Applying the patch fixes the
polarity.
