Some USB controllers can receive or send multiple data packets then
generate one interrupt. This mechanism can reduce the number of data
copies. Extend req buf to accommodate this.

Trying to reduce the size of the docker image, I found files and folders to be deleted.
For now, I have commented Swift from the Dockerfile because the package is too large.
sphinx recommends myst-parser for markdown conversion:

m2r2 is not supported for Python versions >= 3.12 so
we can't build Documentation for example on latest Arch Linux
by the way myst-parser detected a bad link to SECURITY.md that is now fixed
This commit ensures that RTC data is properly allocated in the RTC
segment in the linker. This fixes the reported problem about using
the legacy bootloader and RTC.
There are 2 CMake compile errors during the protected build mode. One is forget to add library for nuttx_user, another is the wrong macro used when compile wqueue.

This PR configures the BL808 MMU to cache the the User Text, Data and Heap. We enable the T-Head MMU Flags for Shareable, Bufferable and Cacheable, as explained in the previous PR: https://github.com/apache/nuttx/pull/13199
This PR fixes the Slow Memory Access for NuttX Apps on Ox64 BL808 SBC: https://github.com/apache/nuttx/issues/12696. With this fix, Ox64 NuttX CoreMark jumps from 19 to 1,104. (Close to Buildroot Linux CoreMark)
Modified Files:
`arch/risc-v/Kconfig`: Enabled `ARCH_MMU_EXT_THEAD` for BL808 SoC.
In protected build mode, the syscall returns without setting correct value for the CONTROL register, which causes the userspace threads working in privileged mode after syscall.

This PR configures the T-Head MMU to cache the the User Text, Data and Heap. We enable the MMU Flags for Shareable, Bufferable and Cacheable, as explained in this article: https://lupyuen.github.io/articles/plic3#appendix-mmu-caching-for-t-head-c906
This PR fixes the Slow Memory Access for NuttX Apps on BL808 and SG2000 SoCs: https://github.com/apache/nuttx/issues/12696. With this fix, SG2000 NuttX CoreMark jumps from 21 to 2,423. (Close to SG2000 Debian CoreMark)
We introduce a Kconfig Option: `ARCH_MMU_EXT_THEAD` ("System Type > Enable T-Head MMU extension support"). Enabling this Kconfig Option will configure the T-Head MMU to cache the User Text, Data and Heap.
This PR enables the MMU cache for only SG2000 SoC (Milk-V Duo S SBC). The next PR will apply the same settings to BL808 SoC (Pine64 Ox64 SBC).
Modified Files:
`arch/risc-v/Kconfig`: Added Kconfig Option `ARCH_MMU_EXT_THEAD` that will configure the T-Head MMU. Enabled `ARCH_MMU_EXT_THEAD` for SG2000 SoC.
`arch/risc-v/src/common/riscv_mmu.h`: Set the T-Head MMU Flags (Shareable, Bufferable and Cacheable) for User Text, Data and Heap, if `ARCH_MMU_EXT_THEAD` is enabled
`arch/risc-v/src/common/riscv_addrenv.c`: Extended the MMU Flags from 32 bits to 64 bits, to accommodate the T-Head MMU Flags
`arch/risc-v/src/common/riscv_exception.c`: Extended the MMU Flags from 32 bits to 64 bit, to accommodate the T-Head MMU Flags. This code is enabled only for MMU Paging (`CONFIG_PAGING`).
Summary:
- I noticed that nfsmount does not work due to the recent
changes on sockaddr_storage alignment.
- This commit fixes this issue.
Impact:
- None
Testing:
- Tested with sabre-6quad:netnsh_smp (QEMU)

purpose:
To improve the real-time performance of the system, we prefer to perform
as few operations as possible within the interrupt function.
We have designed an interrupt thread for each interrupt,
where all the operations that are not necessary to be handled
in the interrupt function are delegated to be processed by the interrupt thread.
Up_enable_irq will be invoked after isrthread started.
Configuring NuttX and compile:
$ ./tools/configure.sh -l qemu-armv8a:nsh_smp
$ make
Running with qemu
$ qemu-system-aarch64 -cpu cortex-a53 -smp 4 -nographic \
-machine virt,virtualization=on,gic-version=3 \

Prior to this commit, i2c and at24 may be used uninitialized on line
113, 117, 129, and 143 when gd32_at24_wr_test() is called the second
time because these two variables are not static. I don't think making
them static is the correct fix because i2c is released at the end of
this function. Fixed by removing the `if (!initialized)` condition
surrounding the initialization of i2c and at24, making them initialized
at every call to this function.

Add TUNSETCARRIER ioctl, then we may change the carrier state of TUN dynamically. Note that we don't need an ioctl for getting carrier, it can be done by SIOCGIFFLAGS already.
