The sim_bthcisock_interrupt() handler for Bluetooth HCI sockets in the simulatorwas using
an if statement to check for available data on the HCI socket. Thismeant that only a single
packet would be read and processed per interrupt trigger,even if multiple packets were waiting
in the socket buffer.
This led to incomplete data processing: unread packets would remain in the bufferuntil the next
interrupt tick, causing delayed handling of Bluetooth HCI events/commands,packet backlogs,
or missed data in high-throughput scenarios.
This fix replaces the if with a while loop to:
1. Continuously check for and read available data from the HCI socket until no more
packets are present in the buffer.
2. Ensure all pending HCI packets are processed in a single interrupt handler invocation.
3. Eliminate packet backlogs and reduce latency in Bluetooth HCI communication.
The change maintains the same core data reception logic (bthcisock_receive()) butensures it runs
for all available packets, improving the reliability and responsivenessof the simulator's Bluetooth HCI socket implementation.

Changes the default value for CONFIG_BOARD_LOOPSPERMSEC to -1, which is
invalid. All boards that forget to configure this value will encounter a
static assertion at compile time, enforcing that configurations
upstreamed to NuttX have calibrated values for correct delay timings.
Boards which implement ALARM_ARCH or TIMER_ARCH do not rely on the
busy-loop delay implementation and thus only have a run-time check to
ensure proper delay-timings (in the case where delays are used before
the alarm/timer driver is registered).
Some boards already in the NuttX upstream do not have calibrated values,
but there are no users who currently own the board to submit a
calibrated value for the configurations to use. In this scenario, the
value is temporarily set to 0 and a warning is displayed so that users
of these boards are informed of the calibration process.

- Change the board's sd-card speed configuration to just specify the wanted frequency
- Calculate the proper divisors in the driver
- If the sd card frequency exceeds 25 MHz, set the card to high-speed mode
This makes it easier to adjust the operating speed of the sd cards and fixes an error
where cards are being operated in standard mode at over 25MHz speeds. If the speed
is higher than 25MHz, the card needs to be set into high-speed mode.

Fix three issues in the STM32H7 FDCAN SocketCAN driver:
1. Clock configuration: Allow board.h to override STM32_FDCANCLK.
Previously the driver hardcoded STM32_HSE_FREQUENCY, ignoring
any board-specific clock configuration.
2. ILS register bug: Fix putreg32 call that was writing FDCAN_ILS_TCL
constant instead of the computed regval, causing interrupt routing
issues.
3. Extended ID filter size: Increase n_extid from 64 to 128. Despite
the reference manual (RM0433) suggesting 64 max, testing shows
that 128 is required for reliable extended ID frame reception.
With 64, some extended ID frames were silently dropped.

With CONFIG_PAGING enabled and the RISC-V SV39 MMU active, the page fault
handler incorrectly tracked page table levels: `ptprev` pointed to the L1
page table while `ptlevel` indicated L2. This inconsistency caused faulty
virtual address resolution.
This commit fixes the traversal logic to ensure consistent level tracking
across all three page table levels (L1–L3), enabling reliable page fault
handling and on-demand paging.
Additional changes:
- Set PGT_L3_SIZE to 2048 to enable mapping up to 8MB of address space.
- Update knsh_paging config to avoid crashes caused by excessive memory
alignment requirements.
- Add knsh64_paging config to verify this commit works as expected.

INT32_C(x) is currently defined as x ## ll on Xtensa, which

defined as long int on this architecture.
This mismatch can break C++ template overload resolution

Move the board-specific phy initialization from early boot into ifup phase. The
board specific phy initialization may need to implement delays, or bus
communication, for example via i2c bus.
These OS services are not necessarily available yet in arm64_netinitialize, and
PHY initialization is not necessary until the driver actually starts using it.
In addition, this allows the board to reset the ethernet phy at every ifup,
if needed for error recover.
