+ * This file contains MMR definitions for both UV1 & UV2 hubs.
+ *
+ * In general, MMR addresses and structures are identical on both hubs.
+ * These MMRs are identified as:
+ * #define UVH_xxx <address>
+ * union uvh_xxx {
+ * unsigned long v;
+ * struct uvh_int_cmpd_s {
+ * } s;
+ * };
+ *
+ * If the MMR exists on both hub type but has different addresses or
+ * contents, the MMR definition is similar to:
+ * #define UV1H_xxx <uv1 address>
+ * #define UV2H_xxx <uv2address>
+ * #define UVH_xxx (is_uv1_hub() ? UV1H_xxx : UV2H_xxx)

+ * } s1;
+ * struct uv2h_int_cmpd_s { (Full UV2 definition)
+ * } s2;
+ * };
+ *
+ * Only essential difference are enumerated. For example, if the address is
+ * the same for both UV1 & UV2, only a single #define is generated. Likewise,
+ * if the contents is the same for both hubs, only the "s" structure is
+ * generated.
+ *
+ * If the MMR exists on ONLY 1 type of hub, no generic definition is
+ * generated:
+ * #define UVnH_xxx <uvn address>
+ * union uvnh_xxx {

+ * struct uvh_int_cmpd_s {
