Whenever a SPI flash operation is going to take place, it's
necessary to disable both the instruction and data cache. In order
to avoid the other CPU (if SMP is enabled) to retrieve data from
the SPI flash, it needs to be paused until the current SPI flash
operation finishes. All the code that "pauses" the other CPU (in
fact, the CPU spins until `up_cpu_resume` is called) needs to run
from the instruction RAM.

ESP32 and ESP32-S3 should use the ROM-defined versions of the libc
in flat build and, when building the protected mode, in the kernel.
The ROM-defined version of the libc functions can't be used in the
userspace, however, because it isn't allowed to access the memory
region in flash directly from the userspace. That being said,
`LIBC_PREVENT_STRING_KERNEL` should be selected to avoid building
any implementation of the libc, being the ROM-defined versions
linked instead.
NuttX's software implemented version of the libc will be built in
the userspace. Also, the assembly-defined version of some of the
libc functions (`XTENSA_xxx`) may also be selected to be used in
the userspace.

Make low/full speed devices work with EHCI while OHCI is disabled. A

will also allow the optional use of a full speed hub between the
high speed hub and the low/full speed device. A recursive mutex is
used to avoid deadlocks.
Move the mapping functionality from up_shmat/shmdt into two generic

This fix was discovered by Sylvio Alves from Espressif!
Instead of using Espressif's emulated NVS to save Wi-Fi data, use
`wapi`s wireless configure initialization mechanism for saving

instead); 2) avoids initialization problems of the emulated NVS
when SMP is enabled (the Wi-Fi driver tries to initialize it before
the actual partition is initialized); and 3) enables reconnecting
using `wapi reconnect` command and connect the device automatically
on bringup if `CONFIG_NETUTILS_NETINIT` is selected.

Devices connected to the same USB bus should have unique function addresses.
This was not true for root hubs with multiple ports. After this change,
enumeration is more reliable on the sama5d3-xplained board when both root hub
ports are used.
This change amounts to using one usbhost_devaddr_s object per root hub
instead of one per root hub port. For the majority of boards only one
root hub port is available so no change in behavior should be expected.

- putreg32() is used the wrong way around (reg, val) instead of (val, reg)
- MPFS_SPI_FRAMESIZE is not a register, FSIZE is the name
- Clear all interrupts _before_ writing the FIFO, this prevents a race
condition where a short transmission completes before the interrupt is
enabled.
in SMP, signal processing cannot be nested, we use xcp.sigdeliver to identify whether there is currently a signal being processed, but this state does not match the actual situation
One possible scenario is that signal processing has already been completed, but an interrupt occurs, resulting in xcp.sigdeliver not being correctly set to NULL,
At this point, a new signal arrives, which can only be placed in the queue and cannot be processed immediately
Our solution is that signal processing and signal complete status are set in the same critical section, which can ensure status synchronization

Invalidate operations at DDI0246H_l2c310_r3p3_trm:
If there is a stale entry in the L2 cache, the system enables the invalidation of
the L1 cache. But before the controller invalidates the L2 cache, it allocates a
line from the L2 cache to an L1 cache.
The robust code sequence for invalidation with a non-exclusive cache arrangement is:
1. InvalLevel2 Address ; forces the address out past level 2
2. CACHE SYNC ; Ensures completion of the L2 inval
3. InvalLevel1 Address ; This is broadcast within the cluster
4. DSB ; Ensure completion of the inval as far as Level 2.
This sequence ensures that, if there is an allocation to L1 after the L1 invalidation, the data
picked up is the new data and not stale data from the L2

Any new boards added should set CONFIG_STM32_USE_LEGACY_PINMAP=n and
fully define the pins in board.hf1
Pinmaps should not have contained GPIO_SPEED_xxx settings.
This is board dependent.
This change adds CONFIG_STM32_USE_LEGACY_PINMAP to allow for
lazy migration to using pinmaps without speeds.
The work required to do this can be aided by running tools/stm32_pinmap_tool.py.
The tools will take a board.h file and a legacy pinmap and outut the required
changes that one needs to make to a board.h file.
Eventually, STM32_USE_LEGACY_PINMAP will be deprecated and the legacy
pinmaps removed from NuttX.

The text describes an issue related to the running task in code.
The running task is only used when calling the _assert function
to indicate the task that was running before an exception occurred.
However, the current code only updates the running task during
irq_dispatch, which is suitable for ARM-M architecture but not
for ARM-A or ARM-R architecture, because their context switches
are not done through irq handler. Therefore, if the following
process is followed, the value of the running task will be incorrect:
1. task1 is running, this_task()=task1
2. do_irq is executed, setting running task()=task1
3. task1 switches to task2
4. task2 is running and generates a data abort
5. In the data abort, the _assert function is called,
and the running task obtained is still task1, but
the actual task that generated the exception is task2.

Over-drive can be forced to a given state by adding define to the
board.h configuration file:
#define STM32_VOS_OVERDRIVE 1 - force over-drive enabled,
#define STM32_VOS_OVERDRIVE 0 - force over-drive disabled,
#undef STM32_VOS_OVERDRIVE - autoselect over-drive by the default RCC logic
It seems that over-drive is not required for ULPI but it can be a workaround solution for boards with poor signal integration.
Higher core voltage means faster clock signal edges, which may be sufficient to synchronize the high-speed clock and data on poorly designed boards.
Over-drive can be forced to a given state by adding define to the
board.h configuration file:
#define STM32_VOS_OVERDRIVE 1 - force over-drive enabled,
#define STM32_VOS_OVERDRIVE 0 - force over-drive disabled,
#undef STM32_VOS_OVERDRIVE - autoselect over-drive by the default RCC logic
- Remove the temporary "saved" variable when temporarily changing MMU
mappings to access another process's memory. The fact that it has an
address environment is enough to make the choice
- Restore nxflat_addrenv_restore-macro. It was accidentally lost when
the address environment handling was re-factored.
The Inter-Processor Interrupt that pauses the other CPU generates
a level-1 interrupt which sets the PS.EXCM. This level-1 interrupt
is treated as an Exception and the bit PS.EXCM bit is automatically
reset on return from Exception. However, this is not the case here
because we are changing the execution to the signal trampoline.
Restoring the PS register with the PS.EXCM bit set would cause any
other exception to deviate execution to the DEC (double exception
vector), avoiding it to be treated correctly. According to the
xtensa ISA: "The process of taking an interrupt does not clear
the interrupt request. The process does set PS.EXCM to 1, which
disables level-1 interrupts in the interrupt handler. Typically,
the PS.EXCM is reset to 0 by the handler, after it has set up the
stack frame and masked the interrupt." Clean the saved PS.EXCM to
1) avoid an exception from being properly treated and 2) avoid
interrupts to be masked while delivering the signal.
In the previous implementation, PerformanceCounter would cause overflow
after running for a long time, This commit will separate the calculation
of the sec/ms part to avoid this issue, Reference:
