#define FFTC_MAX_NUM_BUTTERFLY_STAGES   (7)
 The Maximum number of butterfly stages supported.
#define FFTC_NUM_INTERNAL_BUFFERS   (3)
 The number of internal buffers used by FFTC for simultaneous input, output and calculation operations. A complete FFTC Engine status snapshot can hence be obtained by putting together the status of all the three buffers.
#define FFTC_MAX_NUM_BLOCKS   (128)
 The maximum number of FFT block sizes that can be specified to the FFTC engine hardware.
#define FFTC_MAX_NUM_TXQUEUES   (4)
 The number of Transmit queues dedicated for FFTC from the CPPI-Queue Manager (QM).
#define FFTC_DEF_CPPI_QUEUE_NUM   (0x3FFF)
 Default value for CPPI Destination queue number.
#define FFTC_DEF_DFT_SIZE   (0x3F)
 Default DFT size.
#define FFTC_MAX_NUM_PS_WORDS   (4)
 Maximum number of PS Info words (32 bit words ) supported by the FFTC engine.

#define FFTC_DEF_CPPI_QUEUE_NUM   (0x3FFF)

Default value for CPPI Destination queue number.

Configure the destination CPPI queue number for any given FFTC queue as this value, and the default CPPI queue number from the CPPI DMA channel configuration is used.

#define FFTC_DEF_DFT_SIZE   (0x3F)

Default DFT size.

Configure the 'DFT_size' field of the Queue X Control Register to this value to indicate to the engine to use DFT Size list to pick up block sizes.
