Consider follow coprocessor configuration case:
\#define XCHAL_CP_NUM 1 /* number of coprocessors */
\#define XCHAL_CP_MAX 2 /* max CP ID + 1 (0 if none) */
\#define XCHAL_CP_MASK 0x02 /* bitmask of all CPs by ID */
\#define XCHAL_CP_PORT_MASK 0x00 /* bitmask of only port CPs */
\
\#define XCHAL_CP1_NAME "AudioEngineLX"
\#define XCHAL_CP1_IDENT AudioEngineLX
\#define XCHAL_CP1_SA_SIZE 208 /* size of state save area */
\#define XCHAL_CP1_SA_ALIGN 8 /* min alignment of save area */
\#define XCHAL_CP_ID_AUDIOENGINELX 1 /* coprocessor ID (0..7) */
In this case, XTENSA_CP_ALLSET is 0x1, but valid coprocessors
bitmap is 0x2, use marco XCHAL_CP_MASK instead, it is bitmap of all
vaild coprocs.

Previous implementation has always expanded the width of the timer to 32-bit.
This feature is not always needed and should be configurable from Kconfig.
This commit changes the FLexPWM driver for iMXRT MCU so that LDOK bits in
Master Control Register are set at once after all channels are configured.
Setting LDOK bit enables the driver to load prescaler, modulus and PWM
values of corresponging submodule and start PWM output. Setting all bits
at once instead of doing it separately can help avoiding the channels to
be out of sync with each other.

Many duplicate code when more chips add-in,
follow arch/arm/include/irq.h method, use chip/irq.h instead.

In levelx(2,3,4,5)_handler, first need to save sp in a12,
then after dispatch_c_isr we can restore sp from a12.

Some toolchain such as xtensa-xcc is unrecognize with constraint letter 'I',
letter 'i' is more common in GNU assembler.

In config with no "CONFIG_SPINLOCK", include arch/spinlock.h will lead to
build error as multi definition with spinlock_t. Nuttx/spinlock.h will
include arch/spinlock.h when needed.

When use poweroff command,host_abort will be called,but may be make __stack_chk_fail irq, and host_abort be called in PANIC(), so bring infinite loop, in turn it can not exit SIM.

Currently the "esp32_spiflash_alloc_mtdpart" allocates a
statically-defined partition from "offset" and "size" set via
Kconfig.
This commit changes the function interface to receive those information
as arguments, enabling the creation of multiple MTD partitions with
different offsets and sizes.

Number of configured ADC channels is currently only defined in board
level section, typically in xxx_adc.c file. This commit introduces
ioctl command ANIOC_GET_NCHANNELS that returns the number of configured
channels which is determined by the driver code. The change can allow the
applications to be more flexible when it comes to multiple ADC devices
with different number of configured channels.
