/*
|
|
* 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.
