16  * DOC: IPA Registers
17  *
18  * IPA registers are located within the "ipa-reg" address space defined by
19  * Device Tree.  The offset of each register within that space is specified
20  * by symbols defined below.  The address space is mapped to virtual memory
21  * space in ipa_mem_init().  All IPA registers are 32 bits wide.
22  *
23  * Certain register types are duplicated for a number of instances of
24  * something.  For example, each IPA endpoint has an set of registers
25  * defining its configuration.  The offset to an endpoint's set of registers
26  * is computed based on an "base" offset, plus an endpoint's ID multiplied
27  * and a "stride" value for the register.  For such registers, the offset is
28  * computed by a function-like macro that takes a parameter used in the
29  * computation.
30  *
31  * Some register offsets depend on execution environment.  For these an "ee"
32  * parameter is supplied to the offset macro.  The "ee" value is a member of
33  * the gsi_ee enumerated type.
34  *
35  * The offset of a register dependent on endpoint id is computed by a macro
36  * that is supplied a parameter "ep".  The "ep" value is assumed to be less
37  * than the maximum endpoint value for the current hardware, and that will
38  * not exceed IPA_ENDPOINT_MAX.
39  *
40  * The offset of registers related to filter and route tables is computed
41  * by a macro that is supplied a parameter "er".  The "er" represents an
42  * endpoint ID for filters, or a route ID for routes.  For filters, the
43  * endpoint ID must be less than IPA_ENDPOINT_MAX, but is further restricted
44  * because not all endpoints support filtering.  For routes, the route ID
45  * must be less than IPA_ROUTE_MAX.
46  *
47  * The offset of registers related to resource types is computed by a macro
48  * that is supplied a parameter "rt".  The "rt" represents a resource type,
49  * which is is a member of the ipa_resource_type_src enumerated type for
50  * source endpoint resources or the ipa_resource_type_dst enumerated type
51  * for destination endpoint resources.
52  *
53  * Some registers encode multiple fields within them.  For these, each field
54  * has a symbol below defining a field mask that encodes both the position
55  * and width of the field within its register.
56  *
57  * In some cases, different versions of IPA hardware use different offset or
58  * field mask values.  In such cases an inline_function(ipa) is used rather
59  * than a MACRO to define the offset or field mask to use.
60  *
61  * Finally, some registers hold bitmasks representing endpoints.  In such
62  * cases the @available field in the @ipa structure defines the "full" set
63  * of valid bits for the register.
