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