emsdp_em7d_esp is a board with secure just like em_starterkit_em7d,
but the secure feature not configed in defconfig file. we need to add
below configs in emsdp_em7d_esp_defconfig files:
CONFIG_ARC_HAS_SECURE=y
CONFIG_TRUSTED_EXECUTION_SECURE=y
when secure feature enabled, we use secure timer for system tick, so
we need to add below macro for secure timer:
#define IRQ_SEC_TIMER0 20

Now when we're finally ready to open QEMU port for ARC
we introduce the first ever platform it supports and in fact does
that quite well - Zephyr RTOS.
For now we only offer support of basic EM & HS code execution,
built-in timers, interrupt controller and set of very simple
peripherals: DW UART & optionally MMIO Virtio devices.

ARC_MPU_VER 2 has a strong requirement in
* size, must be >= 2048 bytes and power of 2
* start address must be aligned to size
It may bring a big waste of memory.
On the other hand, GEN_PRIV_STACK is used for ARC_MPU_VER 2,
it conflicts with MPU_STACK_GUARD.
So considering the limmitations, remove MPU_STACK_GUARD for
ARC_MPU_VER 2

Given that nsim_em can run the tests instead of just building them as
with em_starterkit_em7d, make it a default platform instead of
em_starterkit_em7d to get most of the testing when nsim simulator is
installed on the developer machine.
Tests run are 1000x more useful than just building them, even if we do
not have a large installed base of nsim.

Now when ARC development boards are switched to generic OpenOCD
runner we need to explicitly instruct the runner to load Elf but not
binary image (which is a default for OpenOCD runner).
This might be done either manually adding "--use-elf" option to

boards, which we do exactly now.

Some ARC deveopment boards have q bit funny memory maps.
For example IoT Development Kit board has those areas
that we use in Zephyr:
1. 256 KiB of ICCM @ 0x2000_0000 for code
(i.e. ".text" section goes here)
2. 128 KiB of DCCM @ 0x8000_0000 for data
(i.e. ".data" section goes here)
And so objcopy dumps 0x6000_0000 bytes (which is ~ 1.5Gib or raw data)
in zephyr.hex which gives us ~ 4.3 GiB of resulting zephyr.hex size.
W/o gap filling we're back at normal tens of KiB.
Given we have currently no need to fill the gaps anyways we disable it
for all ARC devboards.

The last core which gets initilaized is used by default by OpenOCD.
Thus if we leave configuration as it was we'll get single-core
binaries executed by core3 while we expect core0 to be used.
We didn't see that problem reviously because we used to use
GDB for binary (actually Elf) loading and execution and there in GDB
we explicitly connected to the OpenOCD port wired to core 0.
Now with "west flash" we use OpenOCD for loading anr running and
we need everything setup correctly from the beginning.

We used to use "em-starterkit" runner for ARC which is

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).

All board defconfig files currently set the architecture in addition to
the board and the SoC, by setting e.g. CONFIG_ARM=y. This spams up
defconfig files.
CONFIG_<arch> symbols currently being set in configuration files also
means that they are configurable (can be changed in menuconfig and in
configuration files), even though changing the architecture won't work,
since other things get set from -DBOARD=<board>. Many boards also allow
changing the architecture symbols independently from the SoC symbols,
which doesn't make sense.
Get rid of all assignments to CONFIG_<arch> symbols and clean up the
relationships between symbols and the configuration interface, like
this:
1. Remove the choice with the CONFIG_<arch> symbols in arch/Kconfig and
turn the CONFIG_<arch> symbols into invisible
(promptless/nonconfigurable) symbols instead.
Getting rid of the choice allows the symbols to be 'select'ed (choice
symbols don't support 'select').
2. Select the right CONFIG_<arch> symbol from the SOC_SERIES_* symbols.
This makes sense since you know the architecture if you know the SoC.
Put the select on the SOC_* symbol instead for boards that don't have
a SOC_SERIES_*.
3. Remove all assignments to CONFIG_<arch> symbols. The assignments
would generate errors now, since the symbols are promptless.
The change was done by grepping for assignments to CONFIG_<arch>
symbols, finding the SOC_SERIES_* (or SOC_*) symbol being set in the
same defconfig file, and putting a 'select' on it instead.
See
https://github.com/ulfalizer/zephyr/commits/hide-arch-syms-unsquashed
for a split-up version of this commit, which will make it easier to see
how stuff was done. This needs to go in as one commit though.
This change is safer than it might seem re. outstanding PRs, because any
assignment to CONFIG_<arch> symbols generates an error now, making
outdated stuff easy to catch.

unit-address and first reg (0x20000) don't match for iccm@0
unit-address and first reg (0x80010000) don't match for dccm@80000000
Since the em_starterkit_em7d_normal has a different base address for
iccm & dccm, and most of the em_starterkit variants have different sizes

Now when SMP support for ARC is available we may introduce a simulation
platform which might be used for testing & development for SMP setups.
One important note is stand-alone nSIM (as well as its "Free" flavour)
doesn't support SMP simulation so we have to switch to use of nSIM via
proprietary MetaWare debugger [1] and so:
1. We introduce new emulation target "mdb"
2. It's only possible to run that platform for those who
have MetaWare tools installed and valid license.
Though QEMU port for ARC is in work at the moment and once we
open that port and it has SMP support we'll switch to it and everybody
will be able to try ARC HS with SMP.

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.
