According to the current design on the armv7-a platform,
only fiq is processed in TEE, while irq and fiq are processed
in REE.
If we enable the irq function in TEE, when we process
some signal-related scenarios in TEE,
such as the ostest sighand testcase, this testcase will
call up_irq_enable() to enable irq interrupt in the
arm_sigdeliver() function. After the signal processing
logic is executed, irq will be disabled again.
During the interval of enabling irq, some external device
irq interrupts will be enabled, but these external device
irqs do not have corresponding handlers registered in TEE,
so an "unexpected irq isr exception" will be triggered.
Therefore, a better implementation is to keep the original
implementation of the up_irq_enable() function, that is,
to enable only fiq in TEE and to enable irq and fiq in REE.
Then for vendor-specific requirements, such as the need to
briefly enable irq during the TEE initialization process
and then disable irq before starting APz in TEE, we directly
provide a separate implementation of enabling irq in the
vendor, without modifying the implementation of the public
up_enable_irq() function.

The Bluetooth network on N62 does not retransmit packet, so no packet
retransmition if we drop one, we will drop packet when tcp_close_eventhandler
is register and invoke by tcp_input. then we will always early return and
never stop, the peer will only close the connection if we send reset packet.
precondition:
close -> register tcp_close_eventhandler;
tcp_input -> tcp_callback(TCP_NEWDATA) -> devif_conn_event -> tcp_close_eventhandler
-> flags &= ~TCP_NEWDATA -> NOT entry tcp_data_event -> conn->recvreq NOT increase
old flow:
tcp_input -> tcp->seqno greater than conn->rcvseq -> tcp_send(TCP_ACK)
with this patch:
tcp_input -> tcp->seqno greater than conn->rcvseq -> !TCP_ESTABLISHED
-> case TCP_FIN_WAIT_1 -> dev->d_len greater than 0 -> tcp_reset

When our netstack is replying packets when processing RX, the replied
packets will be sent without considering of TX quota because we don't
want to drop them. Now we may delay them by pushing them to a queue and
send them later, which can always keep quota working.

Summary:
In the x86 environment, memory does not necessarily start at 0, so when end is 0x0, start = end + 1, and then determine the contents of start, it will cause x86 to cause a crash when accessing an illegal address.
This problem does not occur in the arm environment because arm starts at 0x0, so the content of the 0x1 address is “\0”.

This is a tool for associating discrete IDs with addresses.
This tool is implemented through the red-black tree method provided by <sys/tree.h>, and the time complexity when calling, searching, and deleting is optimized to O(logn)
The implementation is the moving node operation of two red-black trees
1. When applying for a node, it will first check whether there is an available node in the "removed" tree. If so, the memory address of the node will be reused and moved to the "alloced" tree.
2. If the "removed" tree is an "empty tree", then the node will be requested from the memory and added to the "alloced" tree
3. Similarly, when removing a node, we set the address pointed to in the node to "NULL" and move it to the "removed" tree. Next time we alloc the node, we can reduce the overhead caused by memory application
For now, we still have something that can be optimized, and that is the memory elimination mechanism of the "removed tree". The current implementation will only release all the content under the "removed" tree when the idtree is destroyed.

If per tick is set to 10ms, it will cause nxsig_usleep(1000) in the
sdio driver to sleep for 19ms, which is much longer than the
expected 1ms, resulting in very low write performance. Add option to
reduce CPU hogging by using sched_yield(), though it may also affect
write performance when the CPU is busy.
