Always write zeroes to this bit field.
Number of bytes to pass through ECC. This is the GPMI transfer count plus the syndrome count that will be
inserted into the stream by the ECC. In DMA2ECC_MODE this count must match the
HW_GPMI_CTRL0_XFER_COUNT. A value of zero will transfer 64K words.
Pointer to an array of one or more 512 byte payload buffers.
Always write zeroes to this bit field.
