/*
* 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 + 0 x0000 .
* - Bits 63 - 32 are a 32 - bit word at base + 0 x0000 ( numerically - lower )
* - Bits 31 - 0 are a 32 - bit word at base + 0 x0004 ( 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 + 0 x0000 , followed by a
* write of 0 x80000000 to base + 0 x0004 , which would " execute " the
* reset .
*
* Of course , since MCFG 63 - 32 is all zero , we could cheat and simply
* write 0 x8000000 to base + 0 x0004 , 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 .
