55979aa3a5 arm: Add more flash and ram size options to i.MX RT MPU config
Adds 8 MB and 64 MB flash size options, which correspond to the two
external flashes (qspi flash and hyperflash) on the mimxrt1050_evk
board. Adds a 32 MB SRAM size option, which corresponds to the external
sdram on the board.

7f271b8689 cc3220sf: soc: Update PRCM call to allow use of ROM API
The API in the current SDK version is rom-patched, and uses
prcm.c code in the driverlib directory.

But, the PRCMMCU3200Init() API call should be prefixed by MAP_
to allow the option to use the ROM API in a future TI SDK version.

3d69198843 arm_mpu: fix off-by-one in mpu_buffer_validate
The loop that checks the MPU region permissions incorrectly
iterates from (num_region + 1) to 1. This should be
(num_region - 1) to 0. This results in the wrong regions
being checked and possible overflow for any implementation
that uses the max region value of 0xFF.

547ed9b563 kconfig: Make 'source' non-globbing and use 'gsource'
Until now, Zephyr has used a patched Kconfiglib that turns 'source' into
a globbing source (by replacing 'source' with 'gsource' at the token
level). There's two problems with this:

  - The patch needs to be maintained separately

  - Misspelled filenames are silently ignored, as they look like glob
    patterns that don't match anything

Fix it as follows:

  1. Replace all 'source' statements that use wildcards with 'gsource'

  2. Remove the custom Kconfiglib patch so that 'source' no longer globs

The sed pattern '/source.*[*?]/s/source/gsource/' was run over all
Kconfig* files to do the replacement.

source's that use environment variables that might contain glob patterns
were manually changed to gsource.

Building the docs in doc/ is a good test, as doc/Makefile deliberately
sets the environment variables to glob up as many Kconfig files as
possible.

57e80e5345 ext: mcux: Reorganize imported drivers into soc family subfolders
We have been combining imported mcux drivers into a flattened directory
structure to maximize driver reuse, but the introduction of additional
nxp soc families (lpc and imx) to zephyr has introduced driver naming
conflicts. This caused us to rename and modify imported files, such as
fsl_gpio.c/h, to make them unique across all three nxp soc families.
This makes updating the the mcux drivers complicated, especially for the
lpc family.

Reoganize the mcux drivers into soc family subfolders, so we can just
copy all the drivers from an mcux distribution (which is done on an
soc-basis) into the appropriate soc family folder. Undo all of the
naming changes that occurred when lpc and imx drivers were originally
imported. Undo the accidental squashing of the kinetis watchdog and dcdc
drivers that occurred when the imx drivers were introduced.

The drawback to this approach is that we have duplicate files when the
same hw ip modules exist in multiple soc families, however there are
only few cases where this occurs, such as fsl_lpuart and fsl_trng.

16472cafcf arch: x86: Use retpolines in core assembly routines
In order to mitigate Spectre variant 2 (branch target injection), use
retpolines for indirect jumps and calls.

The newly-added hidden CONFIG_X86_NO_SPECTRE flag, which is disabled
by default, must be set by a x86 SoC if its CPU performs speculative
execution.  Most targets supported by Zephyr do not, so this is
set to "y" by default.

A new setting, CONFIG_RETPOLINE, has been added to the "Security
Options" sections, and that will be enabled by default if
CONFIG_X86_NO_SPECTRE is disabled.

8606fabf74 kernel: Scheduler refactoring: use _reschedule_*() always
There was a somewhat promiscuous pattern in the kernel where IPC
mechanisms would do something that might effect the current thread
choice, then check _must_switch_threads() (or occasionally
__must_switch_threads -- don't ask, the distinction is being replaced
by real English words), sometimes _is_in_isr() (but not always, even
in contexts where that looks like it would be a mistake), and then
call _Swap() if everything is OK, otherwise releasing the irq_lock().
Sometimes this was done directly, sometimes via the inverted test,
sometimes (poll, heh) by doing the test when the thread state was
modified and then needlessly passing the result up the call stack to
the point of the _Swap().

And some places were just calling _reschedule_threads(), which did all
this already.

Unify all this madness.  The old _reschedule_threads() function has
split into two variants: _reschedule_yield() and
_reschedule_noyield().  The latter is the "normal" one that respects
the cooperative priority of the current thread (i.e. it won't switch
out even if there is a higher priority thread ready -- the current
thread has to pend itself first), the former is used in the handful of
places where code was doing a swap unconditionally, just to preserve
precise behavior across the refactor.  I'm not at all convinced it
should exist...
