16  * Architecture-specific register access methods
17  *
18  * CAAM's bus-addressable registers are 64 bits internally.
19  * They have been wired to be safely accessible on 32-bit
20  * architectures, however. Registers were organized such
21  * that (a) they can be contained in 32 bits, (b) if not, then they
22  * can be treated as two 32-bit entities, or finally (c) if they
23  * must be treated as a single 64-bit value, then this can safely
24  * be done with two 32-bit cycles.
25  *
26  * For 32-bit operations on 64-bit values, CAAM follows the same
27  * 64-bit register access conventions as it's predecessors, in that
28  * writes are "triggered" by a write to the register at the numerically
29  * higher address, thus, a full 64-bit write cycle requires a write
30  * to the lower address, followed by a write to the higher address,
31  * which will latch/execute the write cycle.
32  *
33  * For example, let's assume a SW reset of CAAM through the master
34  * configuration register.
35  * - SWRST is in bit 31 of MCFG.
36  * - MCFG begins at base+0x0000.
37  * - Bits 63-32 are a 32-bit word at base+0x0000 (numerically-lower)
38  * - Bits 31-0 are a 32-bit word at base+0x0004 (numerically-higher)
39  *
40  * (and on Power, the convention is 0-31, 32-63, I know...)
41  *
42  * Assuming a 64-bit write to this MCFG to perform a software reset
43  * would then require a write of 0 to base+0x0000, followed by a
44  * write of 0x80000000 to base+0x0004, which would "execute" the
45  * reset.
46  *
47  * Of course, since MCFG 63-32 is all zero, we could cheat and simply
48  * write 0x8000000 to base+0x0004, and the reset would work fine.
49  * However, since CAAM does contain some write-and-read-intended
50  * 64-bit registers, this code defines 64-bit access methods for
51  * the sake of internal consistency and simplicity, and so that a
52  * clean transition to 64-bit is possible when it becomes necessary.
53  *
54  * There are limitations to this that the developer must recognize.
55  * 32-bit architectures cannot enforce an atomic-64 operation,
56  * Therefore:
57  *
58  * - On writes, since the HW is assumed to latch the cycle on the
59  *   write of the higher-numeric-address word, then ordered
60  *   writes work OK.
61  *
62  * - For reads, where a register contains a relevant value of more
63  *   that 32 bits, the hardware employs logic to latch the other
64  *   "half" of the data until read, ensuring an accurate value.
65  *   This is of particular relevance when dealing with CAAM's
66  *   performance counters.
