/*
 * BCM570x memory map. The internal memory layout varies somewhat
 * depending on whether or not we have external SSRAM attached.
 * The BCM5700 can have up to 16MB of external memory. The BCM5701
 * is apparently not designed to use external SSRAM. The mappings
 * up to the first 4 send rings are the same for both internal and
 * external memory configurations. Note that mini RX ring space is
 * only available with external SSRAM configurations, which means
 * the mini RX ring is not supported on the BCM5701.
 *
 * The NIC's memory can be accessed by the host in one of 3 ways:
 *
 * 1) Indirect register access. The MEMWIN_BASEADDR and MEMWIN_DATA
 *    registers in PCI config space can be used to read any 32-bit
 *    address within the NIC's memory.
 *
 * 2) Memory window access. The MEMWIN_BASEADDR register in PCI config
 *    space can be used in conjunction with the memory window in the
 *    device register space at offset 0x8000 to read any 32K chunk
 *    of NIC memory.
 *
 * 3) Flat mode. If the 'flat mode' bit in the PCI state register is
 *    set, the device I/O mapping consumes 32MB of host address space,
 *    allowing all of the registers and internal NIC memory to be
 *    accessed directly. NIC memory addresses are offset by 0x01000000.
 *    Flat mode consumes so much host address space that it is not
 *    recommended.
