+ * Falcon hardware access
+ *
+ **************************************************************************
+ *
+ * Notes on locking strategy:
+ *
+ * Most Falcon registers require 16-byte (or 8-byte, for SRAM
+ * registers) atomic writes which necessitates locking.
+ * Under normal operation few writes to the Falcon BAR are made and these
+ * registers (EVQ_RPTR_REG, RX_DESC_UPD_REG and TX_DESC_UPD_REG) are special
+ * cased to allow 4-byte (hence lockless) accesses.
+ *
+ * It *is* safe to write to these 4-byte registers in the middle of an
+ * access to an 8-byte or 16-byte register.  We therefore use a
+ * spinlock to protect accesses to the larger registers, but no locks
+ * for the 4-byte registers.
+ *
+ * A write barrier is needed to ensure that DW3 is written after DW0/1/2
+ * due to the way the 16byte registers are "collected" in the Falcon BIU
+ *
+ * We also lock when carrying out reads, to ensure consistency of the
+ * data (made possible since the BIU reads all 128 bits into a cache).
+ * Reads are very rare, so this isn't a significant performance
+ * impact.  (Most data transferred from NIC to host is DMAed directly
+ * into host memory).
+ *
+ * I/O BAR access uses locks for both reads and writes (but is only provided
+ * for testing purposes).
