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