David Hendricks 558614d4d3 rk3288: Re-write spi_xfer() to support full duplex ... This change re-writes the spi_xfer() function to support full-duplex transfers. Even though the code looks much different, the same basic algorithm for setting up the transfer is used. The main difference is that reads from rxdr and writes to txdr occur simultaneously and accounting is more complicated, so I separated the higher-level accounting portion from the low-level FIFO handling portion to simplify things.
