As the flash banks are memory mapped stored code can be executed directly from flash (XIP), also there is additional hardware logic to prefetch and cache contents to improve execution performance. These flash can also be used to store user data (like environment). Flash erase and programming are handled by on-chip NVM controller. Driver implemented driver model but MTD is not really support.

mtd: add altera quadspi driver 2015-11-12T00:26:58+00:00 Thomas Chou thomas@wytron.com.tw 2015-11-09T06:56:02+00:00 38a0f36e83e1d707eceab3c31da65a22c8140bb3 Add Altera Generic Quad SPI Controller support. The controller converts SPI NOR flash to parallel flash interface. So it is not like other SPI flash, but rather like CFI flash. Signed-off-by: Thomas Chou <thomas@wytron.com.tw>
