- * Reads on the Blackfin are speculative. In Blackfin terms, this means they
- * can be interrupted at any time (even after they have been issued on to the
- * external bus), and re-issued after the interrupt occurs.
- *
- * If a FIFO is sitting on the end of the read, it will see two reads,
- * when the core only sees one. The FIFO receives the read which is cancelled,
- * and not delivered to the core.
- *
- * 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
- * Using the dma related functions are recommended for transfering large
- * buffers in/out of FIFOs.
