This revises canm230:pnsh in a few ways:
- adjusting linker scripts structure,
- asserting PMP setting results,
- adjusting configs for both k230d and k230 devices.

Larger RX/TX buffers might be required for both FD and FD_BSW modes.
Default bit timing values are also changed since the original ones
did not provide correct results for default SAMv7 board clock selection
(150 MHz clock frequency). The current values provide correct bit timing
with sample point as close to 87.5 %.

This adds field type to canioc_bittiming_s structure that allows
to set/obtain bit timing for both CAN CC and CAN FD.
CANIOC_GET_BITTIMING is now bidirectional: user specifies type field
and gets other fields from the controller.
The commit also updates current CAN FD capable controllers using the
ioctl. The type is not checked for classical CAN only controllers
and nominal bit timing is returned regardless of type value.

This adds enablers for setting various clocks to some default
values. Also, this provides helpers to grant nonsecure access
to a number of clocks. Bootloader may utilize these to make
the system boot in a deterministic manner.

The link script of NuttX Simulator is generated through compilation
options. This PR will support configure special data sections in
kconfig to meet the support of 3rd party applications.
we need to follow the syntax of linker script. In 3rd-party applications, some data will be labeled as section:
| a.c:
| struct task_s a __attribute__((section(".data.custom.taska")));
| b.c:
| struct task_s b __attribute__((section(".data.custom.taskb")));
Data of the same type struct can be placed in a fixed location to reduce the overhead caused by searching:
| .data :
| {
| _custom_data_table_start = .;
| KEEP(*(.data.custom.*))
| _custom_data_table_end = .;
| }
Such section declare can be configured via Kconfig in the PR:
| CONFIG_SIM_CUSTOM_DATA_SECTION=" .data : { _custom_data_table_start = .; KEEP(*(.data.custom.*)) _custom_data_table_end = .; } "

In the algorithm there is a subtraction (int - unsigned), which results (potentially overflowed)
unsigned.
Passing this to macro ABS and the assigning to int doesn't work ( unsigned is always >= 0 ).
Fix this by replacing (dangerous) ABS macro with stdlib's standard "int abs(int)"
and change the substraction to (int - int).

This is an initial FlexSPI SPI NOR MTD driver for IMX9
This supprts M25P SPI NOR on FlexSPI for now, and can later be extended to other
SPINOR devices if needed. The following configurations are needed to use this driver:
CONFIG_IMX9_FLEXSPI_NOR=y
CONFIG_MTD_M25P=y
In addition, board initialization logic needs to call the imx9_flexspi_nor_initialize
to receive a pointer to the mtd device.

This commit implements a character driver for the general purpose ADC of the BL808, based on the hardware scanning functionality. The driver supports setting different conversion resolutions and the order of channels to be scanned via menuconfig.
Following warnings were caused by incorrect naming of few defines.

The Simple Boot feature for Espressif chips is a method of booting
that doesn't depend on a 2nd stage bootloader. Its not the
intention to replace a 2nd stage bootloader such as MCUboot and
ESP-IDF bootloader, but to have a minimal and straight-forward way
of booting, and also simplify the building.
This commit also removes deprecated code and makes this bootloader
configuration as default for esp32 targets and removes the need
for running 'make bootloader' command for it.

This current driver does not handle well netpkts used in the
write buffers.
I learned about this document:
https://github.com/apache/nuttx/blob/master/Documentation/components/net/netdriver.rst
After I ported and contributed the original driver.
However from the document, I understand these types of drivers are
simpler to implement and I could simplify the driver and handle
correctly the TCP write buffers.
Add addrenv support for x86_64.
For now we support mapping on PT level, so PD, PDT and PML4 are static
