Andrey Smirnov 358ba762d9 crypto: caam - enable prediction resistance in HRWNG 
Instantiate CAAM RNG with prediction resistance enabled to improve its
quality (with PR on DRNG is forced to reseed from TRNG every time
random data is generated).

Management Complex firmware with version lower than 10.20.0
doesn't provide prediction resistance support. Consider this
and only instantiate rng when mc f/w version is lower.

/*
* 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.
