+Overview
+
+DESCRIPTION
+
+SEC 4 h/w can process requests from 2 types of sources.
+1. DPAA Queue Interface (HW interface between Queue Manager & SEC 4).
+2. Job Rings (HW interface between cores & SEC 4 registers).
+
+High Speed Data Path Configuration:
+
+HW interface between QM & SEC 4 and also BM & SEC 4, on DPAA-enabled parts
+such as the P4080. The number of simultaneous dequeues the QI can make is
+equal to the number of Descriptor Controller (DECO) engines in a particular
+SEC version. E.g., the SEC 4.0 in the P4080 has 5 DECOs and can thus
+dequeue from 5 subportals simultaneously.
+
+Job Ring Data Path Configuration:
+
+Each JR is located on a separate 4k page, they may (or may not) be made visible
+in the memory partition devoted to a particular core. The P4080 has 4 JRs, so
+up to 4 JRs can be configured; and all 4 JRs process requests in parallel.
+

+P4080 SEC 4 Node
+
+Description
+
+ Node defines the base address of the SEC 4 block.
+ This block specifies the address range of all global
+ configuration registers for the SEC 4 block. It
+ also receives interrupts from the Run Time Integrity Check
+ (RTIC) function within the SEC 4 block.

+ * 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.
