6d12ee19e2 arch: Move the DUMP_ON_EXIT logic after nxtask_exit. 
Otherwise we will try to dump the state of the current task, however the
exit handler has already started doing some cleanup and invalidated its
group.  Accessing the group from dumponexit will crash.

An INVSTATE UsageFault is raised if a LE instruction is executed and FPSCR.LTPSIZE does not read as four.
When a new floating-point context is created and FPCCR.ASPEN is set to zero it is the responsibility of software
to correctly initialize FPSCR.LTPSIZE.

ff210e1c2d arch/stack_color: correct the end address of stack color 
The different optimization of compilers will cause ambiguity in
obtaining sp through up_getsp() in arm_stack_color(), if compile
with clang and enable the optimization flag (-Ofast), up_getsp()
call will be earlier than push {r0-r9,lr}, the end address of color
stack will overlap with saved registers.

Compile line:
clang --target=arm-none-eabi -c "-Ofast" -fno-builtin -march=armv8.1-m.main+mve.fp+fp.dp \

a98a599cb9 arm/cortex-[a|r]: IRQ Switch return should with shadow SPSR 
The SPSR is used to store the current value of the CPSR when an exception
is taken so that it can be restored after handling the exception.
Each exception handling mode can access its own SPSR.

User mode and System mode do not have an SPSR because they are not
exception handling modes.

    arch/arm: optimize context switch speed

    The current context save implementation saves registers of each task
    to xcp context, which is unnecessary because most of the arm registers are
    already saved in the task stack, this commit replace the xcp context with
    stack context to improve context switching performance and reduce the tcb
    space occupation of tcb instance.

7b9978883c arch/arm: optimize context switch speed 
The current context save implementation saves registers of each task
to xcp context, which is unnecessary because most of the arm registers are
already saved in the task stack, this commit replace the xcp context with
stack context to improve context switching performance and reduce the tcb
space occupation of tcb instance.

State of problem:

   are registered with write permissions
 - Some drivers that do not support read operation (does not
   have read handler or ioctl do not perform any read actions)
   are registered with read permissions
 - Some drivers are registered with execute permissions

Solution:
 - Iterate code where register_driver() is used and change 'mode'
   parameter to reflect the actual read/write operations executed
   by a driver
 - Remove execute permissions from 'mode' parameter

5c1c939cdc stm32u5: Architecture Support for STM32U5 
Architecture support for STMicroelectronics STMU585xx MCUs.  This is
based on corresponding code for STM32L5, but has been considerably
adjusted.  Tested with a B-U585I-IOT02A board and a simple NSH
configuration, but only running NuttX in the non-secure world with
TrustedFirmware-M.

56b3fc0ef9 arch/arm/src/samv7: added support for PWM driver 
This commit adds initial support for PWM driver to SAM MCU series.
Only general PWM on PWMH output is currently supported, complementary
output on PWML is not allowed. The current state of the driver also does
not support external triggering of other perihperals.

Multichannel option is supported. The functionality of the driver was
tested on an example pwm application and with a real time control system.

This change fix the regression that was introduced with
https://github.com/apache/incubator-nuttx/pull/4904

In case if D-Cache in configured in Write-Through mode there is
Cortex-M7 erata 1313001 that describes a situation when linefill
buffer or cache contains stale data. Even if progmem write loop
does not fully matches the description there is a possibility
to program stale data if there is no DMB instruction after each
write operation to progmem latch buffer.

74e692b3c1 stm32f7:sdmmc invalidate before DMA to avoid eviction overwrite 
For FAT the same buffer is used for read and writes, there
  is a possibility a cache line is dirty. But the fs is
  not dirty and will not write the sector to disk. This can
  be seen  https://github.com/PX4/NuttX/pull/175

  When the system is busy that cache line can be evicted after the
  RX DMA has completed and overwrite the data in memory. The solution
  is to invalidate before the DMA to prevent an evection causing an
  overwite, and after the DMA it to insure coherency.
