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.
