* Add driver for the ST M95xxx SPI EEPROMAlbin Tonnerre2009-08-09-0/+118
| | | | | | | | This chip is used in a number of boards manufactured by Calao-Systems which should be supported soon. This driver provides the necessary spi_read and spi_write functions necessary to communicate with the chip. Signed-off-by: Albin Tonnerre <albin.tonnerre@free-electrons.com>

* sf: sst: fix sector sizeMike Frysinger2009-07-06-4/+4
| | | | | | | | Looks like when I was encoding the sector sizes, I forgot to divide by 8 (due to the stupid marketing driven process that declares all sizes in useless megabits and not megabytes). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* sf: stmicro: dont send 4 bytes when reading status registerMike Frysinger2009-04-02-3/+3
| | | | | | | | | | | | I can't find anywhere in the datasheet that says the status register needs 3 dummy bytes sent to it before being able to read back the first real result. Tests on a Blackfin board show that after writing the opcode, the status register starts coming back immediately. So only write out the read status register opcode before polling the result.

* sf: set common timeouts in seconds, not millisecondsMike Frysinger2009-04-02-3/+6
| | | | | | | | | | | Since timeouts are only hit when there is a problem in the system, we don't want to prematurely timeout on a functioning setup. Thus having low timeouts (in milliseconds) doesn't gain us anything in the production case, but rather increases likely hood of causing problems where none otherwise exist.

* sf: always read 5 bytes for the idcodeMike Frysinger2009-04-02-11/+5
| | | | | | | | | | | | Some SPI flash drivers like to have extended id information available (like the spansion flash), so rather than making it re-issue the ID cmd to get at the last 2 bytes, have the common code read 5 bytes rather than just 3. This also matches the Linux behavior where it always reads 5 id bytes from all flashes.

* sf: stmicro: drop redundant id readMike Frysinger2009-04-02-7/+1
| | | | | | | | | | The common SPI flash code reads the idcode and passes it down to the SPI flash driver, so there is no need to read it again ourselves.

* spi flash: fix crash due to spi flash miscommunicationBrad Bozarth2009-01-24-2/+4
| | | | | | | | | | | 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/+616
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>
