Summary:
- I noticed that DEBUGASSERTION() happens when executing
an ELF application
- This commit fixes this issue by re-mapping the address
to SYSBUS in up_module_text_free()
Impact:
- None
Testing:
- Tested with spresense (both DEBUG_ASSERTIONS=n and y)

Summary:
- In cxd56xx, ldrex/strex behavior is slightly different from
other Arm architectures. Dummy strex must be issued to release
the exclusive load & store unit.
Impact:
- SMP only
Testing:
- Tested with spresense:smp
- Tested with spresese:wifi_smp, spresense:rndis_smp
- NOTE: CONFIG_CXD56_TESTSET=y must be removed from defconfigs

Drop to user-space in kernel/protected build with up_pthread_exit,
now all pthread_cleanup functions executed in user mode.
* A new syscall SYS_pthread_exit added
* A new tcb flag TCB_FLAG_CANCEL_DOING added
* up_pthread_exit implemented for riscv/arm arch

If the subcore configuration, which is mainly used in the Spresense
Arduino environment, is enabled, the serial console has been already
initialized by maincore. Then, don't need to re-initialize the UART1
serial driver.
ADC driver does not support multiple open and close. It causes the memory
corruption by multiple free. This commit fixes this problem by introducing
the reference counter.
If the system clock is changed during loading gnssfw, gnss open may be
failed. So this commit prohibits clock change until loading gnssfw is
completed.
There is an issue that the next alarm is expired immediately after
canceling a RTC alarm. Fixed alarm settings to be completely cleared
when canceling an RTC alarm.
If the system clock is changed during the SPI transfer, the SPI data can
be corrupted. So this commit prohibits the clock change during SPI transfer,
and keep the clock until the transfer is completed.
Introduce PM_CPUFREQLOCK_FLAG_HOLD into the frequency lock mechanism in
power manager, which is used to keep the current frequency without clock
change, for example, during the transfer of a periphral.
UART driver is stopped and re-started during a clock change. When a UART
interrupt is generated in each process, the unexpected behavior will
occur and a console will get stuck with UART driver. This commit fixed
each process is performed atomically.
arch: Allocate the space from the beginning in up_stack_frame
and modify the affected portion:
1.Correct the stack dump and check
2.Allocate tls_info_s by up_stack_frame too
3.Move the stack fork allocation from arch to sched

All supported arch uses a push-down stack:
The stack grows toward lower addresses in memory. The stack pointer
register points to the lowest, valid working address (the "top" of
the stack). Items on the stack are referenced as positive(include zero)
word offsets from sp.
Which means that for stack in the [begin, begin + size):
1.The initial SP point to begin + size
2.push equals sub and then store
3.pop equals load and then add

This change makes it so that the timeout is set as part of the SDIO_WAITENABLE call instead of the SDIO_EVENTWAIT call. By doing so, you eliminate all opportunity for a race condition.
stm32h7:sdmmc Check if busy ended early
Because a thread of gnss receiver is created by pthread in the
AppBringUp task, the thread would be killed when AppBringUp
task exits.
Change to use kthread_create instead of pthread_create to prevent
this issue.
cxd56_gnss.c uses file descriptor operation from next change.
0536953 Kernel module should prefer functions with nx/kmm prefix
But this change need to add fcntl.h in include header.
So, add missing header.
Summary:
- This commit adds CPU activity LED feature to cxd56_idle.c and cx56_irq.c
- An LED for the current CPU will turn off before calling WFI
- An LED for the current CPU will turn on when an interrupt happens
Impact:
- CONFIG_ARCH_LEDS_CPU_ACTIVITY=y only
Testing:
- defconfigs will be commited later.

Summary:
- The original commit was added to avoid hardfault but the
root cause was the stack corruption which has been fixed by
the previous commit. So let me revert the original commit.
Impact:
- SMP only
Testing:
- spresense:rndis_smp with nxplayer + telnet
