Strongly-Ordered requires aligned access unless
caching is enabled.
Normal memory
Accesses to normal memory region are idempotent...
- unaligned accesses can be supported
With CONFIG_ARMV7M_DCACHE the cache maintenance operation
are not present. Or if CONFIG_ARMV7M_DCACHE_WRITETHROUGH
is on then buffering operations are no-ops.
This change enables MPU_RASR_C and MPU_RASR_B if
CONFIG_ARMV7M_DCACHE is only set.
if CONFIG_ARMV7M_DCACHE_WRITETHROUGH is set then only
MPU_RASR_C is enabled.
N.B When caching is disalbed unaligned access may cause hard faults
so add -mno-unaligned-access
It is always safe to enable Buffering in FLASH to achive unaligned
access leniency, as it is not written to.
the SDIO clock is not enabled when the bus goes to the idle state, that, in turn, breaks
IRQ delivering mechanism over DAT[1]/IRQ SDIO line to the host.

When NuttX is booted from a foreign (non NuttX)
bootloader. There as a possibility that the
bootloader configured the MPU, in an
incompatible way for the NuttX memory usage.
The option to reset the MPU before it is initialized
may not succeed if the bss and data initialization
code violated the previous MPU configurations.
Added herein are ARM_MPU_RESET and
ARM_MPU_EARLY_RESET. The former can be used
If the system is capable of booting and running
NuttX MPU configuration code without an MPU
violation. The latter is used if the system can
not run the bss and data initialization code.
These are options so that a NuttX may be configured to
not clobber a bootloader MPU configuration in a system
that is architected to share the MPU configuration task.

If we repeatedly call up_cpu_pause and up_cpu_resume, there would be
cases where the next call to up_cpu_pause happens while the other CPU is
still responding to the previous resume request. In this case the
DEBUGASSERT will trigger. We should allow the first CPU to wait until the
other CPU has finished responding to the resume request.

Repeated automated sercon, serdis on VBUS proved to fail
for CDCACM DATA IN (device Serial TX). The root cause was
that the EP was left active after disconnect. This resulted
in the first serial write falling to kick-off the EP IN request.
That should restart the EP ISR.

Because:
* It's very confusing to have cc as LD.
* I don't see what "-nostartfiles -nodefaultlibs" in LDFLAGS are
supposed to do when we use LD directly. It would be simpler to

This commit changes the FLexPWM driver for iMXRT MCU so that LDOK bits in
Master Control Register are set at once after all channels are configured.
Setting LDOK bit enables the driver to load prescaler, modulus and PWM
values of corresponging submodule and start PWM output. Setting all bits
at once instead of doing it separately can help avoiding the channels to
be out of sync with each other.

Number of configured ADC channels is currently only defined in board
level section, typically in xxx_adc.c file. This commit introduces
ioctl command ANIOC_GET_NCHANNELS that returns the number of configured
channels which is determined by the driver code. The change can allow the
applications to be more flexible when it comes to multiple ADC devices
with different number of configured channels.

It seems to be caused by the corrupted or wrong CPSR restored on return
from exception. NuttX restores the context using code like this:
msr spsr, r1
GCC translates this to:
msr spsr_fc, r1
As a result, not all SPSR fields are updated on exception return. This
should be:
msr spsr_fsxc, r1
