// DWC2 controller: use DMA for data transfer
// For processors with data cache enabled, USB endpoint buffer region
// (defined by CFG_TUSB_MEM_SECTION) must be declared as non-cacheable.
// For example, on Cortex-M7 the MPU region can be configured as normal
// non-cacheable, with RASR register value: TEX=1 C=0 B=0 S=0.
