Serge Semin 7e31cea7d1 spi: dw: Use relaxed IO-methods to access FIFOs ... In accordance with [1] the relaxed methods are guaranteed to be ordered with respect to other accesses from the same CPU thread to the same peripheral. This is what we need during the data read/write from/to the controller FIFOs being executed within a single IRQ handler or a kernel task. Such optimization shall significantly speed the data reader and writer up. For instance, the relaxed IO-accessors utilization on Baikal-T1 lets the driver to support the SPI memory operations with bus frequency three-fold faster than if normal IO-accessors would be used.
