Instead of writing one word to the txfifo and then wait until one is received in the rxfifo we can write while the txfifos are not full and read as long the rxfifos contain data. This makes transfers for the m25p80 driver around 7 times faster here. Unlike the last version this time we only optimize the common case with 8 bits per word and SPI_LSB_FIRST cleared. The other cases would require more bit shuffling of the data. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> |
