The name used in Tensilica support file core-isa.h for all vendors is
`XCHAL_NUM_INTLEVELS`.
Use a new name may be confused by newer porting xtensa arch.

This feature depends on frame pointer, "-fno-omit-frame-pointer" is mandatory
This feature can not be used in THUMB2 mode if you are using GCC toolchain,

In AArch32, the frame pointer is stored in register R11 for ARM code or register R7 for Thumb code.
In AArch64, the frame pointer is stored in register X29.

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.

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

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.

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

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.

When SIM_SPI is valid, a specified Linux SPI device ‘spidevN.P’(N is bus number and P is CS number) is attached to nuttx simulator, shown as 'spi0' under /dev. One may type spi command (need SPITOOL valid) in NSH to control the Linux SPI and exchange data, other devices such sensors can use it to debug in simulator on a Ubuntu PC. Note that a USB<>SPI module (e.g. CH341A/B) should be plugged in to achieve Linux SPI ports.

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.
