GPT timer driver previously used "restart mode", where the timer would
count to a given value, then rollover. In this mode, "Any write access
to the Compare register of Channel 1 will reset the GPT counter". Since
a write to the compare register takes affect after 1 cycle of the
module's bus clock, and the bus clock is not synchonized with the GPT
module's low frequency counter clock, writing to the compare register
will induce a counter reset, and can cause the GPT to lose time
synchronization. This can induce time drift over time.
To fix this, rework the GPT driver to use "free run" mode. Note that
free run mode is not used directly, rather the GPT is configured to
reset on a tick boundary at boot, and then the second compare register
is used to set capture points. This way, the GPT interrupt will always
fire at a tick boundary, and no calculations are needed to handle
the counter rollover.

Only include crtbegin.o and crtend.o when LIBGCC_DIR is defined.
Since LIBGCC_DIR is not defined when compiling for posix
architecture, crt{begin,end}.o cannot be referred to via
LIBGCC_DIR.
Also note that, when using llvm/clang, crt{begin,end}S.o are
automatically for native_posix which collide with symbols in
crt{begin,end}.o. So there is no point in making LIBGCC_DIR
available for native_posix under llvm/clang.

This adds a new linker property specifically for passing
"-no-pie" to linker. Older binutils' LD (<= 2.36) do not
support this flag and will behave erratically if set. It
would parse "-no-pie" separately as "-n" and "-o-pie",
which would result in the output file being "-pie"
instead of "zephyr*.elf". Moreover, LLVM lld does not
support -no-pie but --no-pie (note the extra hyphen).
By having no-pie as a linker property, we can pass
correct no-pie flag to these linkers (or none at all).

This adds a new output variable to FindGnuLd.cmake to indicate
if ld.bfd is found. Since we now ask the compilers for their
preferred ld.bfd linker, it may not match using the existing
string equal test to ${CROSS_COMPILE}ld.bfd. So set the new
variable GNULD_LINKER_IS_BFD to true if ld.bfd, and use it to
pass an extra argument to compiler to make it use ld.bfd.

This flag is intended to signify to the boot system that device runtime

Changed the watchdog driver used by the ACE platform from
snps,designware-watchdog to intel,adsp-watchdog.
Signed-off-by: Adrian Warecki <adrian.warecki@intel.com>
Added a new watchdog driver which can handle a multiple wdt_dw instances
and can control the pause signal.
The mlt platform has three designware watchdogs, one for each core.
I decided to create a separate intel watchdog driver for the following
reasons:
1. All three devices share the same interrupt number. Each watchdog reports
an interrupt to the core to which it has been assigned. The same interrupt
number cannot be used by multiple devices in the device tree. So, it would
be assigned to only one device. The other dw watchdog devices would use
this assignment, even though it would not be described for them in the dt.
The interrupt handler function in dw watchdog checks the interrupt flag.
If the interrupt was connected to the first watchdog, and the second or
third watchdog signal an interrupt, the interrupt handler of the first
device would ignore it because it would not have set the interrupt flag.
The watchdog device don't knows anything about the existence of the others
devices.
2. The designware watchdog only supports a hardware pause signal. It cannot
be paused programmatically. On the mtl platform, there is a separate group
of control registers for all per-core watchdogs. There are GPIO-like
registers that allows control of a hardware pause signal for subordinate
watchdogs. This separate block is shared by all three watchdogs.
3. The base addresses of the subordinate watchdogs are read from the
aforementioned control registers. As a result, in the device tree we have
only one base address for the intel watchdog, which points to the pause
control registers and containing the base addresses of the subordinate
devices.

freeing up the address space they take up. These new APIs allow for these
