If device encryption is not enabled by eFuse, and partiton mark as
encrypted flag, then encrypted MTD is used.
That is no problem in write and read operation, but failed while
using spi_flash_mmap(...) since de-encrypt is not processed.
So, back to use non-encrypted MTD following API Guide:
If flash encryption is not enabled, the flag "encrypted" has no effect
- i.MX93 LPUARTs have 16-byte RX and TX FIFOs. Take those into use and correct some related register definitions
- There is no reason to loop inside interrupt handler, remove the looping

- Remove GPIO (SW) based flow control. It didn't work, and pure HW flow control seems to work fine
- Remove some unneeded ifdefs and change bit-field flags to booleans to clean up the code

we encounter some situations where the structure is not defined, or the
returned data types do not match the expectations. Refer to the EtherCAT
implementation of other systems and add relevant definitions.

- When opening a NFS file in append mode, its file pointer was at offset
0 instead of the end of file.
- When creating a NFS file, the response read pointer wasn't advanced
after reading the attributes_follows bool, which caused the attributes
to be off by 4 bytes. For example, the file size read the GID.

Use VSCode + clangd plugin to develop the code, the clangd will save the
metadata into .cache directory, it is about the compile_commands.json:
cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=True
Add the .cache into .gitignore for friendly clangd development environment.

For kernel builds, shared memory is automatically aligned to page size.
For flat and protected builds, we align the memory size to the CPU cache
line size.
Failure to align memory properly could result in partial data read/write
by the CPU and peripherals, potentially causing data corruption during
cache flushes or invalidations.

User may set CONFIG_MM_REGIONS=1 on purpose to disable CCM.
This is a completely normal system config and should not be treated as error.
I found this problem trying to run Renode with stm32f4discovery/nsh but
Renode doesn't support CCM so we have to disable it
If the core id needs to be included in the hardware register
calculation, up_cpu_index() should be used instead of this_cpu().

1. Enable timer and irq finally to make sure timer callback was already
registered. When the CPU resets, the values of some generic timer
registers are undefined. Enabling the timer interrupt in advance may
cause the timer to trigger early while the timer callback is not yet
registered. This results in the timer ISR being executed, which masks
the timer interrupt. Since the timer callback is not registered at
this point, the timer interrupt is not unmasked, further causing the
system scheduler to hang.
2. Remove timer mask for one-shot timer and that's in isr,
irq/fiq is disabled. Masking generic timer is not necessary, and it
may introduce risks, otherwise, mask/unmask must be pair in all
situations.

After recent changes on nuttx-apps (not limited to, but related
to nuttx-apps#2738, for instance), the stack usage for the NSH
task increased, causing stack overflows under specific situations
(when running `ps` command, for instance). This commit increases
the init task stack size to avoid it. Please note that, even before
these changes, the stack usage of the NSH task was around 90% and,
then, increasing the stack size of it was recommended.
