Discovered with pylint3.
Use the placeholder name '_' for unproblematic unused variables. It's
what I'm used to, and pylint knows not to flag it.
Python tip:
for i in range(n):
some_list.append(0)
can be replaced with
some_list += n*[0]
Similarly, 3*'\t' gives '\t\t\t'.
(Relevant here because pylint flagged the loop index as unused.)
To do integer division in Python 3, use // instead of /.

In case of double buffering (two capture buffers), the CSI is
frequently starved because of a lack of buffer in the active pool.
You can find below an example of double buffering scenario:
FREE_BUF ACTIVE_BUF
start: 0 2
frame0_complete: 0 1 (no buffer to load in active)
resubmit_frame0: 1 1
frame1_complete: 1 0 (CSI stopped, active buf = 0)
resubmit_frame1: 2 0
0 -> 2 (CSI restarted)
This patch solves this issue by loading buffer to active at submit
time.
FREE_BUF ACTIVE_BUF
start: 0 2
frame0_complete: 0 1
resubmit_frame0: 1 1
0 -> 2 (Direct load to active)
frame1_complete: 0 1
resubmit_frame1: 1 1
0 -> 2

Adding additional workarounds to cc_pal.h that are necessary due to the
fact that the POSIX subsys does not integrate well with other parts of
Zephyr, as per discussion in #13444. These workarounds are needed when
fcntl.h is included, to avoid symbols from being redefined in POSIX
headers. They disable some POSIX headers and define what is necessary
for the code to compile.
We should aim to remove these when the integration story has improved.

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

Adds a new config HAS_MCUX_FTFX to conditionalize the mcux flash driver
on socs that support it. Selects HAS_MCUX_FTFX on all kinetis socs
except kw40z, because even though this soc has the relevant hardware,
its CMSIS header file is not compatible with the mcux flash driver in
ext/.
This change also prevents enabling the mcux flash driver on lpc and imx
rt boards.

This patch unifies the way NRFX_RTC* Kconfig options are handled in
nrfx_config*.h files for particular Nordic SoCs, so that these files
are easier in maintenance. For nRF52810 and nRF9160, this means adding
of support for these options, since it was missing.

The NRFX_UARTE* Kconfig options were handled only in the nrfx_config
for nRF9160. This commit updates remaining nrfx_configs, so that these
options are handled uniformly for all Nordic SoCs.
The NRFX_UART option, although defined in ext/hal/nordic/Kconfig,
were not supported in any of nrfx_config files, effectively making
it impossible to use nrfx_uart.c driver. This commit corrects this.

Functions which have to be located in RAM are placed by SiLabs library
code in section '.ram'. Corresponding section used by Zephyr is called
'.ramfunc'. This patch renames SiLabs naming to match Zephyr's.
This solution was chosen over adding '.ram' function to Zephyr linker
scripts not to pollute them. However, this patch needs to be reapplied
every time SiLabs library version is updated.

The latest update of the SAM E70 HAL (commit 6ad7e13608) shifted the
GMAC priority queues related registers by 4 bytes. It is not cleared
yet, if it is change is a mistake or a change from 0 based indexing
to 1 based indexing. Indeed the main queue is the number 0, and the
first priority queue is therefore the number 1.
In the meantime revert that change, and use the old registers addresses
matching the datasheet.
