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