After first called from uart open, the dw8250_uart_configure
API cannot be called again. Otherwise, this will mess up the
device, and uart will not act properly to interrupt again.
Analysis: Configure uart device will close recive interrupte,
causing uart device to malfunction.
Solution: After configure uart device, enable the device's
recive interrupte.

This patch fixes GCC build support for FRDM-MCXC444.
* Updated compiler flags to Cortex-M0 without FPU.
* Updated linker script to add RT-Thread const tables.
Supports both big and little cores of RISC-V C906,
but does not support ARM cores. Currently, only UART
drivers are supported on the peripherals.

* bsp: nxp/mcx/mcxn: SPI: Added missing bracket and re-format code.
The closing bracket is missing from SPI6 struct.
Introduced since commit fc1cfd6d3627ba8460d514e7913bd307e8b1d567 .
Use standard rt_spi_device->cs_pin instead of user_data pointer.

For bsp/cvitek, all drivers related files are moved to the directory
bsp/cvitek/drivers, so the drivers_path_prefix processing in the

Analysis: The IRQ_MAX_NR value of c906_little is wrong.
interrupt.h relies on IRQ_MAX_NR defined in rtconfig.h but
does not explicitly include this header file.
Solution: Change IRQ_MAX_NR to the correct value 61 in
the datasheet. Explicitly include rtconfig.h in interrupt.h.

Analysis: The IRQ_MAX_NR value of cv18xx_risc-v is wrong.
The wrong IRQ_MAX_NR will cause the install of an interrupt
number larger than its value to fail.
Solution: Change IRQ_MAX_NR to the correct value 101 in
the datasheet.

The aarch64 core of duo on the master cannot enter the
console interface. It can only print the RT flag and hold it.
Analysis: The latest commit that can work is ae6a328 ("Add
psoc62, 61 config"). This phenomenon will occur after adding
754c59a ("[Feature] DFS mount auto by kernel parameters").
The specific reason is that when aarch bsp enables the device
tree, the current u-boot will pass in bootargs, which contains
"root=/dev/mmcblk0p2 rootwait rw", which means that the
kernel is required to wait until the rootfs in /dev/mmcblk0p2
loaded successfully. However, the current aarch64 bsp default
does not implement sdmmc device mounting, causing the
kernel file system mounting module (rootfs_mnt_init() of
components/drivers/core/mnt.c) to enter an infinite loop waiting.
Solution: At present, we do not plan to modify the startup
parameters of u-boot. The temporary solution adopted is to
create a pseudo /dev/mmcblk0p2 device during the board
initialization process, and then cancel the pseudo device
after mnt is completed. This allows the kernel boot to be
completed successfully.

* add support a423 at hwi2c driver
* add .ignore_format.yml
In the original Sconstruct script, `GetDepend('__STACKSIZE__')`
is placed before the call to `PrepareBuilding()`, which causes
the value of `GetDepend('__STACKSIZE__')` to always be False,
and the value of `__STACKSIZE__` in `link_stacksize.lds` will
not be updated.
Solution: move the call if `PrepareBuilding()` ahead.
Also sync and update the .config and rtconfig.h, plus the
link_stacksize.lds.

Currently, the documents under bsp/cvitek are a bit
messy. There are currently four readme files:
- bsp/cvitek/README.md (Chinese)
- bsp/cvitek/c906_little/README.md (Chinese/English)
- bsp/cvitek/cv18xx_aarch64/README.md (Chinese)
- bsp/cvitek/cv18xx_risc-v/README.md (Chinese/English)
Regarding the working mode of the big + small cores, it
is meaningless to describe the small core alone, or the
large core alone. This can also be seen in the existing
files. The readme of the small core will also introduce
the programming of the large core, and vice versa.
Considering that the official default mode is
C906B + C906L. ARM large core can be treataed as a
special case. So the document structure is modified as
follows:
- Remove `bsp/cvitek/c906_little/README.md` and
`bsp/cvitek/cv18xx_risc-v/README.md`, merge them all
into `bsp/cvitek/README.md`
- Add a link to `bsp/cvitek/cv18xx_aarch64/README.md`
in `bsp/cvitek/README.md`
FIXME: The modified document does not provide English
version. Is it really necessary?
