Andy Ross eb1ef50b6b arch/xtensa: General cleanup, remove dead code
There was a bunch of dead historical cruft floating around in the
arch/xtensa tree, left over from older code versions.  It's time to do
a cleanup pass.  This is entirely refactoring and size optimization,
no behavior changes on any in-tree devices should be present.

Among the more notable changes:

+ xtensa_context.h offered an elaborate API to deal with a stack frame
  and context layout that we no longer use.

+ xtensa_rtos.h was entirely dead code

+ xtensa_timer.h was a parallel abstraction layer implementing in the
  architecture layer what we're already doing in our timer driver.

+ The architecture thread structs (_callee_saved and _thread_arch)
  aren't used by current code, and had dead fields that were removed.
  Unfortunately for standards compliance and C++ compatibility it's
  not possible to leave an empty struct here, so they have a single
  byte field.

+ xtensa_api.h was really just some interrupt management inlines used
  by irq.h, so fold that code into the outer header.

+ Remove the stale assembly offsets.  This architecture doesn't use
  that facility.

All told, more than a thousand lines have been removed.  Not bad.

Andrew Boie 6fd6b7e50a xtensa: remove legacy arch implementation
We re-wrote the xtensa arch code, but never got around
to purging the old implementation.

Removed those boards which hadn't been moved to the new
arch code. These were all xt-sim simulator targets and not
real hardware.

Fixes: #18138

Anas Nashif 5eb90ec169 cleanup: include/: move misc/__assert.h to sys/__assert.h
move misc/__assert.h to sys/__assert.h and
create a shim for backward-compatibility.

No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

Patrik Flykt 4344e27c26 all: Update reserved function names
Update reserved function names starting with one underscore, replacing
them as follows:
   '_k_' with 'z_'
   '_K_' with 'Z_'
   '_handler_' with 'z_handl_'
   '_Cstart' with 'z_cstart'
   '_Swap' with 'z_swap'

This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.

Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.

Various generator scripts have also been updated as well as perf,
linker and usb files. These are
   drivers/serial/uart_handlers.c
   include/linker/kobject-text.ld
   kernel/include/syscall_handler.h
   scripts/gen_kobject_list.py
   scripts/gen_syscall_header.py

Kumar Gala bf53ebf2c8 arch: convert to using newly introduced integer sized types
Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.  There are few places we dont convert over to the new
types because of compatiability with ext/HALs or for ease of transition
at this point.  Fixup a few of the PRI formatters so we build with newlib.

Kumar Gala 789081673f Introduce new sized integer typedefs
This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t.  This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.

We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.

We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.
