+/*
+ * CRB Root Command
+ * A single set of crbs is used across all physical/virtual
+ * functions for capability queries, initialization, and
+ * context creation/destruction.
+ *
+ * There are 4 CRBS:
+ *					Command/Response CRB
+ *					Argument1 CRB
+ *					Argument2 CRB
+ *					Argument3 CRB
+ *					Signature CRB
+ *
+ * The cmd/rsp crb is always intiated by the host via
+ * a command code and always responded by the card with
+ * a response code. The cmd and rsp codes are disjoint.
+ * The sequence of use is always CMD, RSP, CLEAR CMD.
+ *
+ * The arguments are for passing in command specific
+ * and response specific parameters/data.
+ *
+ * The signature is composed of a magic value, the
+ * pci function id, and a command sequence id:
+ *		[7:0]  = pci function
+ *		[15:8]  = version
+ *		[31:16] = magic of 0xcafe
+ *
+ *	The pci function allows the card to take correct
+ *	action for the given particular commands.
+ *	The firmware will attempt to detect
+ *	an errant driver that has died while holding
+ *	the root crb hardware lock. Such an error condition
+ *	shows up as the cmd/rsp crb stuck in a non-clear state.
+ *
+ * Interface Sequence:
+ *	 Host always makes requests and firmware always responds.
+ *	 Note that data field is always set prior to command field.
+ *
+ *		[READ]             CMD/RSP CRB      ARGUMENT FIELD
