The divider should be rounded to the next full integer to ensure that
the resulting SPI frequency is <= target frequency, i.e. the SPI is
not overclocked.
After this, RISC-V fully supports the kmap interface.
Due to the current design limitations of having only a single L2 table
per process, the kernel kmap area cannot be mapped via any user page
directory, as they do not contain the page tables to address that range.
So a "kernel address environment" is added, which can do the mapping. The
mapping is reflected to every process as only the root page directory (L1)
is copied to users, which means every change to L2 / L3 tables will be
seen by every user.

Adds support for hardware timestamping of received Ethernet packets.
The timestamp is available to applications using socket option SO_TIMESTAMP.
Optionally, the Ethernet PTP timer can be used as system high-resolution RTC.
In this mode it supports fine resolution rate adjustment.
Alternatively other time source for CLOCK_REALTIME can be used, and the
PTP timestamps are converted by sampling the clocks and computing the
difference. This results in a few microseconds of uncertainty.
The halt operation may be causes the raw epread data segment lost, and
usb ep_queue can handle when the usb buffer is full. so remove the

If using flow control with a high CTS the thread may be
blocked forever on the second transmit attempt due to waiting
on the txdma semaphore. The calling thread can then never
make progress and release any resources it has taken, thus
may cause a deadlock in other parts of the system.
The implementation differs in behavior from interrupt-driven
TX. It should not implicitly wait on a taken semaphore but
return immediately and let the upper layers decide on what to
do next.

This commit sets the BLE's interrupt as a IRAM-enabled interrupt,
which enables it to run during a SPI flash operation. This enables
us to create a cache to off-load semaphores and message queues
operations and treat them when the SPI flash operation is finished.
By doing that, we avoid packet losses during a SPI flash operation.
This commit provides an interface to register ISRs that run from
IRAM and keeps track of the non-IRAM interrupts. It enables, for
instance, to avoid disabling all the interrupts during a SPI flash
operation: IRAM-enabled ISRs are, then, able to run during these
operations.
It also makes the code look more similar to the ESP32-S3 SPI flash
implementation by creating a common `esp32_spiflash_init` that is
responsible to create the SPI flash operation tasks. The function
intended to initialize the SPI flash partions was, then, renamed to
`board_spiflash_init`.
Whenever we enter/leave a critical section, the interrupt status is
saved and, then, restored. However, for the ESP32's BLE adapter,
entering/leaving a critical section is done on separate functions
that need to be registered as a callback.
The status flag was being saved as a global variable. However,
calling nested enter_critical_section would overwrite this global
variable that was storing the previous flag and, when leaving the
last critical section, the restored status would be different from
the one expected. The proposed solution for this issue is to create
a global array to store the interrupt status flags for nested calls.

The implementation differs in behavior from interrupt-driven TX and the
STM32F7 TXDMA . It should not implicitly wait on a taken semaphore but
return immediately and let the upper layers decide on what to do next.
Some APIs are implemented both in common code and CHIP-specific code,
and the link needs to be based on the implementation in CHIP, so move

The DMA can bring in more rx data, than the number of
DMA completions call backs. The call back happen on
idle, 1/2 and full events. But in between these events
the DMA can write more data to the buffers memory that

We do the invalidate on the reads from the fifo memory
if the the DMA as commited since the last read.
Previously, GPIO interrupts were not correctly mapped to the peripheral base register responsible for the interrupt.
Change the IRQ number calculation so the interrupts work correctly on all GPIO peripheral bases.
When ESP32's BLE is enabled, select the option to pin the HCI TX
thread to a specific core. This is necessary to avoid problems
with the BLE task that runs pinned to the PRO CPU (core 0) while
running with SMP enabled.
For TOR: Any size and 4-byte aligned address is required
For NA4: Only size 4 and 4-byte aligned address is good
For NAPOT: Minimum size is 8 bytes, minimum base alignment is 8 bytes,
and size must be power-of-two aligned with base
This commit simplifies these checks and removes all the nonsense added
by a misunderstanding of how the MPFS / Polarfire SoC's PMP works.
These options are just wrong and a result of misunderstanding of the
Polarfire SoC spec. There are no feature limitations in the CPU PMP
implementation -> remove any configuration options added.

or long time data transmission.
The spin_lock in the wlan_recvframe() function that receives
RX data packets from the wireless network card and the critical
section lock in the iob_remove_queue() processing are nested,
which causes the interrupt to be disabled for a longer period
of time, resulting in a risk of deadlock.
When we build NuttX on macOS, it shows many `sed` messages (and the build still completes successfully):
```text
$ tools/configure.sh pinephone:nsh
$ make
sed: illegal option -- r
```
This is due to the Makefiles executing `sed -r` which is not a valid option on macOS.
This PR proposes to change `sed -r` to `sed -E` because:
- `sed -E` on macOS is equivalent to `sed -r` on Linux
- `sed -E` and `sed -r` are aliases according to the GNU `sed` Manual
- `sed -E` is already used in nuttx_add_romfs.cmake, nuttx_add_symtab.cmake and process_config.sh
All kernel memory is mapped paddr=vaddr, so it is trivial to give mapping
for kernel memory. Only interesting region should be kernel RAM, so omit
kernel ROM and don't allow re-mapping it.
It looks like we do not need to send the 9 clock ticks whenever we reset
the FSM. We are already doing this in i2c_reset function if necessary.
This makes the i2c transfers much faster, for example the i2c(-tool) dev

When allocating a CPU interrupt, make sure to select the correct
CPU core to query for it. Simply checking for the current CPU does
not satisfy this requirement because the CPU allocation thread may
be executed by the other core: it's necessary to stick with the
intended CPU passed as an argument of the `esp32s3_setup_irq`.
The registered `task_create_wrapper` receives the `core_id`, but
the current implementation ignores this parameter while calling
`esp_task_create_pinned_to_core`. This commit fix this.
