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