836651b453 drivers: gpio: Refactor drivers to use shared init priority
Refactors all of the on-chip GPIO drivers to use a shared driver class
initialization priority configuration, CONFIG_GPIO_INIT_PRIORITY, to
allow configuring GPIO drivers separately from other devices. This is
similar to other driver classes like I2C and SPI.

Most drivers previously used CONFIG_KERNEL_INIT_PRIORITY_DEFAULT or
CONFIG_KERNEL_INIT_PRIORITY_DEVICE, therefore the default for this new
option is the lower of the two, which means earlier initialization.

Driver-specific options for off-chip I2C- or SPI-based GPIO drivers are
left intact because they often need to be initialized at a different
priority than on-chip GPIO drivers.

b9ed2d33fd drivers: spi: Remove unused Kconfig symbols
Remove SPI_[0-8] and SPI_[0-8]_OP_MODES Kconfig symbols as no driver
uses them anymore.  We also cleanup board and sample code to remove
use of these symbols.

a5b45d9567 boards: Remove Kconfig I2C_[0-9] usage
The Kconfig I2C_[0-9] sybmols don't have any meaning for the majority of
SoCs.  The drivers doesn't utilize them and no sample or test code does
either so we can remove setting them in board Kconfig.defconfig files.

a42a42cd5a kconfig: Replace defconfig singe-symbol 'if's with 'depends on'
Same deal as in commit eddd98f ("kconfig: Replace some single-symbol
'if's with 'depends on'"), for all symbols defined within defconfig
files. See that commit for an explanation.

Maybe 'if's were used originally to mirror the 'if's in the main Kconfig
files, and then it got copied around by people assuming 'if' must work
differently from 'depends on'. It doesn't match in every spot at least.
Better to keep it simple and just consistently use 'depends on' when
it's a single symbol/choice I think. Helps reinforce that 'if' isn't
magic too.

Verified by printing all Kconfig menu nodes (symbols, choices, menus,
etc.) before and after the change and diffing (should show no
difference).

f2fd40e90d ARC: Add support for ARC HS family of CPU cores
The ARC HS is a family of high performance CPUs from Synopsys
capable of running wide range of applications from heavy DPS
calculation to full-scale OS.

Still as with other ARC cores ARC HS might be tailored to
a particular application.

As opposed to EM cores ARC HS cores always have support of unaligned
data access and by default GCC generates such a data layout with
so we have to always enable unaligned data access in runtime otherwise
on attempt to access such data we'd see "Unaligned memory exception".

Note we had to explicitly mention CONFIG_CPU_ARCEM=y in
all current defconfigs as CPU_ARC{EM|HS} are now parts of a
choice so we cannot simply select ether option in board's Kconfig.

And while at it change "-mmpy-option" of ARC EM to "wlh1"
which is the same as previously used "6" but matches
Programmer's Reference Manual (PRM) and is more human-friendly.

40dbec4cd1 ARC: Mention ARC EM family instead of EM4 template
ARC EM4 is just a baseline configuration of ARC EM family of CPU cores.
But with addition of more featuers like caches, DSP extensions etc
we're effectively getting EM6, EM5D etc templates.

So to not confuse users let's talk about families of ARC cores
as that's what makes sense together with extra features but not
templates itself.

3ae52624ff license: cleanup: add SPDX Apache-2.0 license identifier
Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier.  Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.

By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

4638652214 Kconfig: Use 'default' instead of 'def_bool' in Kconfig.defconfig files
This can help find unused symbols. Those end up without a type if
'default' is used instead of 'def_bool', which generates a warning.

Search for "Kconfig.defconfig" in
https://docs.zephyrproject.org/latest/application/kconfig-tips.html for
a longer explanation.

Keep the 'def_bool' for the following symbols, which seem to be
deliberately defined only in Kconfig.defconfig files:

 - ALTERA_AVALON_I2C
 - ALTERA_AVALON_MSGDMA
 - ALTERA_AVALON_PIO
 - ALTERA_AVALON_QSPI
 - ALTERA_AVALON_SYSID
 - CLOCK_CONTROL_IMX_CCM
 - CPU_EM4_DMIPS
 - CPU_EM4_FPUDA
 - CPU_EM4_FPUS
 - FP_FPU_DA
 - I2C_GECKO

fc210ab505 Kconfig: Remove unused symbols defined only in Kconfig.defconfig files
Turning 'def_bool' in Kconfig.defconfig files into 'default' revealed
three unused symbols (confirmed with 'git grep'). Remove them.

Search for "Kconfig.defconfig" in
https://docs.zephyrproject.org/latest/application/kconfig-tips.html for
an explanation of how def_bool->default can reveal undefined symbols.

Removed unused symbols:

 - SPI_DW_CLOCK_GATE

 - PINMUX_MPS2

 - BOARD_XTENSA

Also remove an assignment to the promptless symbol ALTERA_AVALON_SYSID,
in tests/boards/altera_max10/sysid/prj.conf. Assignments to promptless
symbols have no effect.

8d35760fec board: organize boards based on architecture
Introduce an architecture sorting of boards.  This is to allow for
easier maintenance going forward as the number of boards grows.  It
will be easier for any scripts to know the board/arch mapping without
having to maintain an explicit list of what boards are associated with
which arch.  We can also do things like have architecture maintainers
cover reviews and branches for arch/${ARCH} and boards/${ARCH} going
forward.
