Current `CONFIG_PAGING` refers to an experimental implementation
to enable embedded MCUs with some limited RAM space to execute
large programs from some non-random access media.
On-demand paging should be implemented for the kernel mode with
address environment implementation enabled.
Add support for static tcb, applications in some special case can
initialize system resources in advance through static tcb.
| static struct task_tcb_s g_tcb;
|
| memset(&g_tcb, 0, sizeof(struct task_tcb_s));
| g_tcb.cmn.flags = TCB_FLAG_TTYPE_KERNEL;
| nxtask_init(&g_tcb, "PTCB", 101, NULL, 1024, ptcb_task, NULL, NULL, NULL);

change thread0 tcb->xcp.regs
restore_critical_section()
enter_critical_section() done
leave_critical_section()
IRQ leave with restore CURRENT_REGS
ERROR !!!
Reason:
As descript above, cpu0 swith task: thread0 -> thread1, and the
syscall() execute slowly, this time cpu1 pick thread0 to run at
up_cpu_paused(). Then cpu0 syscall execute, cpu1 IRQ leave error.
Resolve:
Move arm64_restorestate() after enter_critical_section() done

In the previous patch, we moved rptun_panic and rptun_dump_all in rptun to rpmsg.
In order to ensure CI pass, this two API in rptun is not removed. So we remove rptun_panic and rptun_dump_all in this patch.

The implementation of assert in linux is as follows:
define assert(expr) (__ASSERT_VOID_CAST (0))
After defining NDEBUG in sqlite, some variables will be undefined,
and referencing variables in assert will cause compilation errors.

According to the standard definition, assert should return a void expression
https://pubs.opengroup.org/onlinepubs/007904875/basedefs/assert.h.html
This patch involves two changes:
If you define the NDEBUG macro, assert does not use any parameters and directly returns a void expression.
assert should return a void expression and cannot use do-while statements.
If the following code , a compilation error will occur.

ALT1250 driver sends an event named LTE_CMDID_RESTARTAPI
to ALT1250 daemon when state is PM_NOARMAL in the function
of prepare registered by pm_register.
It should be possible to use ping without rptun being enabled, so striped rptun_ping out of rptun and rename to rpmsg_ping.

This change adds support for the USB Transport Layer as described
in the bluetooth spec. Isochronous endpoints are not yet supported.
Because of limitations in the NuttX bluetooth stack, only one USB
device can be used. This driver will only allow one USB dongle to
use bluetooth.
A Laird USB BT4.2 dongle (from Mouser) was used for testing:
M/N BT851 1.0 1829, FCC ID:SQGBT850
lsusb: 04b4:f901 Cypress Semiconductor Corp. CYW20704A2
The following commands were used to test from the nsh prompt:
bt bnep0 scan start
bt bnep0 scan stop
bt bnep0 scan get
bt bnep0 info
The Linux gatttool was used to connect over wireless.
With the BDAddr found by "bt bnep0 info", start gatttool using:
gatttool -b BDAddr -I
Connect to the device using:
connect
Read the device name using the GAP device name UUID:
char-read-uuid 2a00
Part of the response is:
value: 41 70 61 63 68 65 20 4e 75 74 74 58
which is the string "Apache NuttX"
