and more closely mimic Linux's directory organization.

+ *
+ * To solve this, interrupts are turned off before reads occur to I/O space.
+ * There are 3 versions of all these functions
+ * - turns interrupts off every read (higher overhead, but lower latency)
+ * - turns interrupts off every loop (low overhead, but longer latency)
+ * - DMA version, which do not suffer from this issue. DMA versions have
+ * different name (prefixed by dma_ ), and are located in
+ * ../kernel/bfin_dma_5xx.c
