ATA interface enable

CONFIG_ATA_ENABLE

  Say Y here to enable the ATA interace from OpenCores. The core has one

  AHB slave interface for accessing all control registers.

ATA register address

CONFIG_ATAIO

  The control registers of the ATA core occupy 256 byte, and are

  mapped in the AHB bus I/O area (0xFFF00000 - 0xFFFFF000). This setting

  defines at which address in the I/O area the registers appear (HADDR[19:8]).

ATA interrupt

CONFIG_ATAIRQ

  Defines which interrupt number the ATA core will generate.

ATA DMA support

CONFIG_ATA_MWDMA

  Say yes here to enable IDE multi-word DMA support (MWDMA).

  This will increase transfer rate compared to the PIO mode,

  but increase area with approxiamtely 5,000 gates. Note that

  DMA is not supported by legacy CF cards, so it makes no sense

  to enable it on CF card sockets.

ATA DMA FIFO depth

CONFIG_ATA_FIFO

  Defines the DMA FIFO depth. Choose 8 or 16.
