Detailed Description

Initialisation descriptor for ra8_flash_init.

MRAM has no MSTP gate (it is the code memory and is always powered) so the only thing the driver needs at init time is the operating frequency the silicon should advertise to the controller via MRCFREQ. cppcheck cannot see callers in tests/ so it flags every field as unused; the suppress comment matches what ra8_acmphs.h does.
