19 * Addressing:
20 *
21 * The Tigon uses 64-bit host addresses, regardless of their actual
22 * length, and it expects a big-endian format. For 32 bit systems the
23 * upper 32 bits of the address are simply ignored (zero), however for
24 * little endian 64 bit systems (Alpha) this looks strange with the
25 * two parts of the address word being swapped.
26 *
27 * The addresses are split in two 32 bit words for all architectures
28 * as some of them are in PCI shared memory and it is necessary to use
29 * readl/writel to access them.
30 *
31 * The addressing code is derived from Pete Wyckoff's work, but
32 * modified to deal properly with readl/writel usage.
