The different optimization of compilers will cause ambiguity in

stack will overlap with saved registers.

    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.

1ded8bbabb Garbage configuration setting in EFM32 code
arch/arm/src/efm32/efm32_start.c:

      /* For the case of the separate user-/kernel-space build, perform whatever
       * platform specific initialization of the user memory is required.
      * Normally this just means initializing the user space .data and .bss
       * segments.
       */

    #ifdef CONFIG_NUTTX_KERNEL
      efm32_userspace();
      showprogress('E');
    #endif

But there is no CONFIG_NUTTX_KERNEL configuration setting.  Comparing this to other architectures it is clear this should be

    #ifdef CONFIG_BUILD_PROTECTED

8defb843aa Remove duplicate linker script definitions
## Summary
A lot of linker scripts were listed twice, once for unix, once for windows.

This PR cleans up the logic so they're only listed once.

 ## Impact
Any opportunity to use a single source of truth and reduce lines of code is a win!

 ## Testing
CI will test all build

41c95da594 register_driver: fix driver modes accross the code
State of problem:
 - Some drivers that do not support write operations (does not
   have write handler or ioctl do not perform any write actions)
   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

commit 328374f4658d11655f268f968f4c6c7a3942f320

   changed the wait to use usleep. This killed the
   write performace from the published values in the
   datasheet of ~100 us to 2 mS per 256 bits. On
   a 1000 per tick config. It can be 10 X worse
   on the default 100 per tick config.

   This changes uses up_udelay.

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.

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.
