struct xxx_lowerhalf_s
{
struct djoy_lowerhalf_s lower;
/* Add more private data here */

This script will help you analyze memdump log files,
analyze the number of occurrences of backtrace,
and output stack information
memdump log files need this format:
pid size addr mem

Summary:
- I noticed that exiting task or pthread causes dataabort if ARCH_ADDRENV=y
- This commit fixes this issue by switching the addrenv correctly
Impact:
- CONFIG_ARCH_ADDRENV=y only
Testing:
- Tested with sabre-6quad:netknsh (not merged yet)

Summary:
- I noticed that when exiting getprime, DEBUGASSERT happens in
nxsem_wait()
- Finally, I found that up_putc() uses nxsem_wait()
- This commit fixes this issue by removing the semaphore.
- Also, up_putc() now calls imx_lowputc()
Impact:
- None
Testing:
- Tested with sabre-6quad:netknsh (not merged yet)

Summary:
- In case of BUILD_KERNEL, NuttX uses USR mode sp and SVC mode sp.
- The kernel runs on SVC mode sp.
- While the kernel is running, up_getsp() cannot get the TLS address.
- The kernel requires tls_get_info() function.
- For the user land, up_getsp() can be used.
- tls_getinfo.c is always compiled and tls_get_info() function is
filtered by macros in the tls_getinfo.c.
Impact:
BUILD_KERNEL
Testing:
test program on custom Cortex-A9 board (BUILD_KERNEL)
ostest on sabre-6quad:smp (QEMU, BUILD_FLAT)

Reason for use sw-interrupt as syscall interrupt:
The xtensa `syscall` instruction can cause SYSCALL interrupt.
But SYSCALL interrupt is same interrupt level with level-one
interrupt.
Nuttx swint can enter `enter_critical_section` and gerenate
interrupt.
