 14 * Addressing:
 15 *
 16 * The Tigon uses 64-bit host addresses, regardless of their actual
 17 * length, and it expects a big-endian format. For 32 bit systems the
 18 * upper 32 bits of the address are simply ignored (zero), however for
 19 * little endian 64 bit systems (Alpha) this looks strange with the
 20 * two parts of the address word being swapped.
 21 *
 22 * The addresses are split in two 32 bit words for all architectures
 23 * as some of them are in PCI shared memory and it is necessary to use
 24 * readl/writel to access them.
 25 *
 26 * The addressing code is derived from Pete Wyckoff's work, but
 27 * modified to deal properly with readl/writel usage.
