* spi flash: fix crash due to spi flash miscommunicationBrad Bozarth2009-01-24-1/+2
| | | | | | | | | | | Higher spi flash layers expect to be given back a pointer that was malloced so that it can free the result, but the lower layers return a pointer that is in the middle of the malloced memory. Reorder the members of the lower spi structures so that things work out.

* SPI Flash subsystemHaavard Skinnemoen2008-06-03-0/+362
This adds a new SPI flash subsystem. Currently, only AT45 DataFlash in non-power-of-two mode is supported, but some preliminary support for other flash types is in place as well. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
