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.

The ARC timer is a MHz-scale cycle counter and works very well with
the new 10 kHz default tick rate. Remove the settings for ARC
hardware.
Note that the nsim board definitions are left at 100 Hz. That is a
software emulation environment that (like qemu) exposes the host clock
as "real" time and thus is subject to clock jitter due to host
scheduling.

The DT spec. only has "okay" and not "ok". The Linux kernel has around
12k "okay"s and 300 "ok"s.
The scripts/dts scripts only check for "disabled", so should be safe re.
those at least.
The replacement was done with

This helps by letting us add checks for when the runner has already
been set. There is documentation saying you can set
-DBOARD_DEBUG_RUNNER at the command line and have it take effect,
which turns out not to be true for a large number of boards.
A status message helps the user debug.

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.

This was never a long-term solution, more of a gross hack
to get test cases working until we could figure out a good
end-to-end solution for memory domains that generated
appropriate linker sections. Now that we have this with
the app shared memory feature, and have converted all tests
to remove it, delete this feature.
To date all userspace APIs have been tagged as 'experimental'
which sidesteps deprecation policies.

There are different interrupt numbers for R22 v R23. Before this was

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

- PINMUX_MPS2

These changes were obtained by running a script created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:
1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
#define X Y)
3. Check if that name is also the name of a Kconfig option
3.a If it is, then do nothing
3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
(.c, .h, .ld)
Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.
Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

The original em7d, em9d and em11d are different configurations of
em_starterkit. They have the same peripherals, e.g. uart, spi, gpio
, ddr. The differences of them are in arc core configurations, interrupt
number assignment.
So em7d, em9d and em11d can be viewed in the same SoC family or SoC
series.
Referring other arch's implementation, this commit merges em7d, em9d
and em11d into the same SoC, named snps_emsk. This will eliminate
unnecessary duplication and make it easier for future maintainment.
