* specific write (store) operation to the MPI peripheral block was getting lost erroneously.
* Following data re-verify loop could catch it during runtime.
*
* As a workaround, we are disabling loop distribute patterns for this function and hence
* compiler does not enforce usage of `memset` (or `memcpy`) calls for this routine. It
* appears that `-ftree-loop-distribute-patterns` was enabled with O2/Os starting from
* GCC-10.x. It is quite possible that there is some issue with DPORT write with sequence of
* store instructions as generated by `memset` call, but for now this should serve as good
* interim workaround without any impact on the performance.
* As a workaround, we are using DPORT_WRITE_REG (volatile writes) wrappers to write to
* the MPI peripheral.

* Please see IDF-6029 for more details.
