16 *
17 * In general, MMR addresses and structures are identical on both hubs.
18 * These MMRs are identified as:
19 * #define UVH_xxx <address>
20 * union uvh_xxx {
21 * unsigned long v;
22 * struct uvh_int_cmpd_s {
23 * } s;
24 * };
25 *
26 * If the MMR exists on both hub type but has different addresses or
27 * contents, the MMR definition is similar to:
28 * #define UV1H_xxx <uv1 address>
29 * #define UV2H_xxx <uv2address>
30 * #define UVH_xxx (is_uv1_hub() ? UV1H_xxx : UV2H_xxx)
31 * union uvh_xxx {
32 * unsigned long v;
33 * struct uv1h_int_cmpd_s { (Common fields only)
34 * } s;
35 * struct uv1h_int_cmpd_s { (Full UV1 definition)
36 * } s1;
37 * struct uv2h_int_cmpd_s { (Full UV2 definition)
38 * } s2;
39 * };
40 *
41 * Only essential difference are enumerated. For example, if the address is
42 * the same for both UV1 & UV2, only a single #define is generated. Likewise,
43 * if the contents is the same for both hubs, only the "s" structure is
44 * generated.
45 *
46 * If the MMR exists on ONLY 1 type of hub, no generic definition is
47 * generated:
48 * #define UVnH_xxx <uvn address>
49 * union uvnh_xxx {
50 * unsigned long v;
51 * struct uvh_int_cmpd_s {
52 * } sn;
53 * };
