e039053546 uart/ns16550, drivers/pcie: add PCI(e) support
A parallel PCI implementation ("pcie") is added with features for PCIe.
In particular, message-signaled interrupts (MSI) are supported, which
are essential to the use of any non-trivial PCIe device.

The NS16550 UART driver is modified to use pcie.

pcie is a complete replacement for the old PCI support ("pci"). It is
smaller, by an order of magnitude, and cleaner. Both pci and pcie can
(and do) coexist in the same builds, but the intent is to rework any
existing drivers that depend on pci and ultimately remove pci entirely.

This patch is large, but things in mirror are smaller than they appear.
Most of the modified files are configuration-related, and are changed
only slightly to accommodate the modified UART driver.

Deficiencies:

64-bit support is minimal. The code works fine with 64-bit capable
devices, but will not cooperate with MMIO regions (or MSI targets) that
have high bits set. This is not needed on any current boards, and is
unlikely to be needed in the future. Only superficial changes would
be required if we change our minds.

The method specifying PCI endpoints in devicetree is somewhat kludgey.
The "right" way would be to hang PCI devices off a topological tree;
while this would be more aesthetically pleasing, I don't think it's
worth the effort, given our non-standard use of devicetree.

4cf4040af0 arc: print human-readable exception info
Right now only numerical values are printed which must
be looked up in the Designware ARCv2 ISA Programmer's
Reference, which is not public.

Add a non-default Kconfig to print more information at
the expense of footprint, and enable it for all the simulator
targets.

We only print code/parameter details for machine check and
protection violations, more may be added later as desired.
This should cover all the exceptions we commonly encounter
for memory protection.

42d330406e Bluetooth: Mesh: Fix qualification test MESH/SR/HM/CFS/BV-02-C
The commit 8d0ef1eb85 attempted to fix
test case MESH/SR/HM/CFS/BV-02-C, however inadvertently ended up
introducing a hidden bug. This bug was unearthed thanks to commit
686f5c79cf. We have to keep always track
of the FastPeriodDivisor state whether we're using it (faults > 0) or
not (faults == 0). Introduce a boolean field to the model publication
that's used to indicate whether the FastPeriodDivisor should be
applied or not, instead of zeroing the divisor when there are no
faults (this would cause wrong behavior when faults appear again).

Additionally, the PTS seems to require that we wait until the end of
the existing period before sending the next Health Current Status,
rather than sending it immediately when the fault count changes.

4e5c093e66 kernel: demote K_THREAD_STACK_BUFFER() to private
This macro is slated for complete removal, as it's not possible
on arches with an MPU stack guard to know the true buffer bounds
without also knowing the runtime state of its associated thread.

As removing this completely would be invasive to where we are
in the 1.14 release, demote to a private kernel Z_ API instead.
The current way that the macro is being used internally will
not cause any undue harm, we just don't want any external code
depending on it.

The final work to remove this (and overhaul stack specification in
general) will take place in 1.15 in the context of #14269

84b1bba8ee codecov: keep "inline" for ALWAYS_INLINE
Previous commit c31e659165 changed
the ALWAYS_INLINE macros to avoid functions being inlined for
the purpose of code coverage. This has a side effect of causing
the text sections of kobject_hash.c and priv_stacks_hash.c
to ballon more than 10 times in size. This is caused by
attaching the unused attribute, which results in all those
functions being in the text sections though they are never
used. So just keep the "inline" there.

This also removes -fno-inline from NO_COVERAGE_FLAGS so these
two files are not compiled with flags related to code coverage.

and to ensure the naming convention makes it clear that the currently

to Slep States and updates the documentation.

a0851c47aa arch: arm: introduce barriers when disabling interrupts
The ARM Cortex-M 321 application note is stressing that if
we disable interrupts by executing CPSID i(f), or by MSR
instructions (on PRIMASK, FAULTMASK registers), there is no
requirement to add barrier instructions after disabling
interupts. However, in ARMv7-M (and ARMv8-M Mainline) we use
BASEPRI, instead. Therefore, if we need the effect of disabling
interrupts to be recongnized immediately we should add barrier
instructions. This commit adds DSB and ISB barriers when
disabling interrupt using BASEPRI in the generic
arm _irq_lock() function as well as in the PendSV handler,
where we need to access kernel globals right after the interrups
are disabled.

b3eb510f5c kernel: fix atomic ops in user mode on some arches
Most CPUs have instructions like LOCK, LDREX/STREX, etc which
allows for atomic operations without locking interrupts that
can be invoked from user mode without complication. They typically
use compiler builtin atomic operations, or custom assembly
to implement them.

However, some CPUs may lack these kinds of instructions, such
as Cortex-M0 or some ARC. They use these C-based atomic
operation implementations instead. Unfortunately these require
grabbing a spinlock to ensure proper concurrency with other
threads and ISRs. Hence, they will trigger an exception when
called from user mode.

For these platforms, which support user mode but not atomic
operation instructions, the atomic API has been exposed as
system calls.

Some of the implementations in atomic_c.c which can be instead
expressed in terms of other atomic operations have been removed.

The kernel test of atomic operations now runs in user mode to
prove that this works.

To support async mode, a new callback argument is added to the API.

212ec9a29a linker: sort app shared mem partition by alignment
If CONFIG_MPU_REQUIRES_POWER_OF_TWO_ALIGNMENT is enabled,
the app shared memory partition may cause waste of memory
due to the need for padding.

For example, tests/subsys/jwt and board mps2_an385:

  z_test_mem_partition: addr 0x20000000, size 52
  z_libc_partition    : addr 0x20000040, size 4
  k_mbedtls_partition : addr 0x20008000, size 32736

    ending at 0x2000ffff, taking up 65536 bytes

With power-of-two size and alignment requirement,
k_mbedtls_partition takes up 32KB memory and needs to be
aligned on 32KB boundary. If the above partitions are
ordered as shown, there needs to be a lot of padding
after z_libc_partition before k_mbedtls_partition can
start. In order to minimize padding, these partitions
need to be sort by size in descending order.

After the changes here,	the partitions are:

  k_mbedtls_partition : addr 0x20000000, size 32736
  z_test_mem_partition: addr 0x20008000, size 52
  z_libc_partition    : addr 0x20008040, size 4

    ending at 0x2000805f, taking up 32864 bytes

With the above example, sorting results in a saving
of 32672 bytes of saving.

c0183fdedd kernel/work_q: Fix locking across multiple queues
There was a detected user error in the code where racing insertions of
k_delayed_work items into different queues would be detected and
flagged as an error (honestly I don't see much value there -- Zephyr
doesn't as a general rule protect against errors like this, and
work_q's are inherently kernel things that don't require
userspace-style checking).

This got broken with spinlockification, where each work_q object got
its own lock, so the single lock wouldn't protect against the other
insert function any more.  As it happens, that was needless.  The core
synchronization on a work_q is in the internal k_queue object anyway
-- the lock in this file was only ever used for (very fast,
noncontending) delayed work insertion.  So go back to a global lock to
preserve the original behavior.

dd01e9997f net/context: Add an option so set/unset packet timestamping
Though core system is able to manage packet timestamping internaly (gptp
requires it for instance), it might be necessary to enable/disable
packet timestamping from net context directly.

Currently this will be only used by the tx timestamp test. So this
support is disabled by default. (And gptp does not require it anyway).

zephyr variables.

The variables which indicate the bounds of the entire
partition now end with "_part_start", "_part_size",
and "_part_end" to make them easy for scripts to
distinguish them from other generated symbols for
data/bss sizes.

Finally, the bss size is not rounded up, this was
