2009-08-09Add driver for the ST M95xxx SPI EEPROMAlbin Tonnerre
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 <[email protected]>

new chips supported:- MX25L1605D, MX25L3205D, MX25L6405D, MX25L12855E out of which MX25L6405D and MX25L12855E tested on Kirkwood platforms Modified the Macronix flash support to use 2 bytes of device id instead of 1 This was required to support MX25L12855E Signed-off-by: Piyush Shah <[email protected]> Signed-off-by: Prafulla Wadaskar <[email protected]> Signed-off-by: Mike Frysinger <[email protected]>

2009-07-06sf: sst: fix sector sizeMike Frysinger
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 <[email protected]>

2009-04-02sf: stmicro: dont send 4 bytes when reading status registerMike Frysinger
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.

2009-04-02sf: set common timeouts in seconds, not millisecondsMike Frysinger
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.

2009-04-02sf: always read 5 bytes for the idcodeMike Frysinger
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.

2009-04-02sf: stmicro: drop redundant id readMike Frysinger
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.

2009-01-24spi flash: fix crash due to spi flash miscommunicationBrad Bozarth
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.

2008-12-16spi/stmicro: fix debug() display of cmdMike Frysinger
