18  * Architecture-specific register access methods
19  *
20  * CAAM's bus-addressable registers are 64 bits internally.
21  * They have been wired to be safely accessible on 32-bit
22  * architectures, however. Registers were organized such
23  * that (a) they can be contained in 32 bits, (b) if not, then they
24  * can be treated as two 32-bit entities, or finally (c) if they
25  * must be treated as a single 64-bit value, then this can safely
26  * be done with two 32-bit cycles.
27  *
28  * For 32-bit operations on 64-bit values, CAAM follows the same
29  * 64-bit register access conventions as it's predecessors, in that
30  * writes are "triggered" by a write to the register at the numerically
31  * higher address, thus, a full 64-bit write cycle requires a write
32  * to the lower address, followed by a write to the higher address,
33  * which will latch/execute the write cycle.
34  *
35  * For example, let's assume a SW reset of CAAM through the master
36  * configuration register.
37  * - SWRST is in bit 31 of MCFG.
38  * - MCFG begins at base+0x0000.
39  * - Bits 63-32 are a 32-bit word at base+0x0000 (numerically-lower)
40  * - Bits 31-0 are a 32-bit word at base+0x0004 (numerically-higher)
41  *
42  * (and on Power, the convention is 0-31, 32-63, I know...)
43  *
44  * Assuming a 64-bit write to this MCFG to perform a software reset
45  * would then require a write of 0 to base+0x0000, followed by a
46  * write of 0x80000000 to base+0x0004, which would "execute" the
47  * reset.
48  *
49  * Of course, since MCFG 63-32 is all zero, we could cheat and simply
50  * write 0x8000000 to base+0x0004, and the reset would work fine.
51  * However, since CAAM does contain some write-and-read-intended
52  * 64-bit registers, this code defines 64-bit access methods for
53  * the sake of internal consistency and simplicity, and so that a
54  * clean transition to 64-bit is possible when it becomes necessary.
55  *
56  * There are limitations to this that the developer must recognize.
57  * 32-bit architectures cannot enforce an atomic-64 operation,
58  * Therefore:
59  *
60  * - On writes, since the HW is assumed to latch the cycle on the
61  *   write of the higher-numeric-address word, then ordered
62  *   writes work OK.
63  *
64  * - For reads, where a register contains a relevant value of more
65  *   that 32 bits, the hardware employs logic to latch the other
66  *   "half" of the data until read, ensuring an accurate value.
67  *   This is of particular relevance when dealing with CAAM's
68  *   performance counters.
