sf: stmicro: dont send 4 bytes when reading status register

2009-04-02T16:51:28+00:00

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 milliseconds

2009-04-02T12:11:31+00:00

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 idcode

2009-04-02T10:50:21+00:00

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 read

2009-04-02T10:50:17+00:00

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 miscommunication

2009-01-24T00:57:40+00:00

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.
