*Custom Section Align*

Type: ``bool``

Help
====

MPU_REQUIRES_POWER_OF_TWO_ALIGNMENT(ARMv7-M) sometimes cause memory
wasting in linker scripts defined memory sections. Use this symbol
to guarantee user custom section align size to avoid more memory used
for respect alignment. But that needs carefully configure MPU region
and sub-regions(ARMv7-M) to cover this feature.
