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.

When the PSRAM is enabled, we should not allocate the TX/RX
buffers there, so we use kmm_calloc here, to make it into IRAM,
so the ethernet controller can read bytes from it.
