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