[RFC PATCH 2/2] mtd: devices: m25p80: Enable spi-nor bounce buffer support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Many SPI controller drivers use DMA to read/write from m25p80 compatible
flashes. Therefore enable bounce buffers support provided by spi-nor
framework to take care of handling vmalloc'd buffers which may not be
DMA'able.
