  14  * Architecture-specific register access methods
  15  *
  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.
  23  *
  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.
  30  *
  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)
  37  *
  38  * (and on Power, the convention is 0-31, 32-63, I know...)
  39  *
  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
  43  * reset.
  44  *
  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.
  51  *
  52  * There are limitations to this that the developer must recognize.
  53  * 32-bit architectures cannot enforce an atomic-64 operation,
  54  * Therefore:
  55  *
  56  * - On writes, since the HW is assumed to latch the cycle on the
  57  *   write of the higher-numeric-address word, then ordered
  58  *   writes work OK.
  59  *
  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.
