This limits the search for Extended BIOS Data Area (EBDA) to
0x80000 to 0x100000 as this is usually the area for it.
If 0000:040e has an address not pointing to this area, it is
probably an invalid address, and should not be de-referenced

Accumulator registers (ACCL, ACCH) are used on HS CPUs not only
in case of FPU usage but also in case of MPY usage. We enable MPY
for all ARCv2 HS in commit
18a24c3f

 ARC: gcc-m-cpu: use -mcpu=archs as a default for ARCv2 HS
but we didn't enable accumulator registers management.

Let's enable accumulator registers save/restore on all ARCv2 HS CPUs
by default.

rv32m1_vega don't boot due to device init ordering and changes with the
device model.  The soc code is looking for a device pointer for the
intmux.  Change to using DEVICE_DT_GET here as that will ensure we get
a valid pointer and by the time we need to utilize the pointer the
intmux driver will have been initialized and thus the device pointer
will be ready.

Also set BUILD_OUTPUT_HEX since we utilize openocd to flash and west
flash is looking for a hex file for openocd targets.

When the host toolchain is used, `-nostdlib` option is not specified
and therefore all default libraries, including the libgcc and its
components, are automatically linked -- so it is not necessary to
manually link them here.

The host toolchain makes use of the host toolchain libraries (i.e.

This commit updates the build system to always detect the libgcc path
for the host platforms regardless of the target architecture.

The native_posix_64 target previously used the x32 ABI (`-mx32`) and
the multilib for this ABI was not commonly available in the x86-64 host
toolchains.

That is no longer the case because native_posix_64 had been updated to
use the x86-64 ABI (`-m64`).

This commit removes the `NOT no_libgcc` condition for the automatic
libgcc path detection.

The `no_libgcc` variable was previously set in this file to exclude
libgcc detection for the x86-64 targets because the x86-64 arch used
x32 ABI (`-mx32`) and the multilib for this ABI was not commonly
available. This is no longer the case (x86-64 targets now use `-m64`)
and libgcc must always be available.

commit 5e9c583c

 ("arch/x86_64: Terrible, awful hackery to
bootstrap entry") introduced a terrible trick which begins execution
at the bottom of .locore with a jump, which then gets replaced with
NOP instructions for the benefit of 16 bit real mode startup of the
other CPUs later on.

But I forgot that EFI enters in 64 bit code natively, and so never
hits that path.  And moving it to the 64 bit setup code doesn't work,
because at that point when we are NOT loaded from EFI, we already have
the Zephyr page tables in place that disallow writes to .locore.

So do it in the EFI loader, which while sort of a weird place, has the
benefit of being in C instead of assembly.

Really all this code needs to go away.  A proper x86 entry
architecture would enter somewhere in the main blob, and .locore
should be a tiny stub we copy in at runtime.

This commit makes C++ exception handling feature depend on the full
version of newlib (i.e. `CONFIG_NEWLIB_LIBC_NANO=n`).

The `nano.specs`, which selects the nano variant of newlib, libstdc++,

lib*c++ is compiled with `-fno-exceptions`.

The `.eh_frame_hdr` and `.eh_frame` ROM sections, which contain read-
only C++ exception handling information, are currently specified in
`cplusplus-ram.ld`, and this can cause the linker output location
counter to take a ROM region address while in the RAM region.

This commit relocates these sections to `cplusplus-rom.ld` in order to
prevent the linker output location counter from getting corrupted.

This commit extends the usability by allowing users to locate the
Zephyr build configuration CMake package outside the Zephyr workspace

`set(ZephyrBuildConfiguration_ROOT <path>)`
