8c0c70ab12 add QSPI memory mapped mode support. tested. QSPI may enter and exit memory mapped mode; while in effect, other operations (e.g. command, memory) will fail with -EBUSY. 2016-04-23 11:54:03 -05:00

499fea73ec basic support for QSPI in STM32L4; verified via 'examples/media' 2016-04-17 21:08:25 -05:00

bef518095f Fix the STM32L4 SPI driver. That SPI driver is quite different. They now handle frames of arbitrary size between 4 and 16 bits. It was broken before a new bit has to be set (rx fifo threshold) to handle <= 8-bit transactions. If not set, the default is 16-bit packed >=8-bit frames and the RXNE bit is never set (it is set when 16-bits are received). weird things as always. 
This also add 8-bit access routines to the data register, because a 16-bit access to the data register when the frame size is below 9 bits is interpreted as a packed dual frame exchange.
