2011-09-12Allow smaller write units in SPI flash drivers.Vadim Bendebury
There is a problem with x86 systems using Intel ICH chips as the SPI controller: whereas the SPI chips allow for 256 byte pages for write transactions, the controllers allow for only 64 bytes per transaction. This causes failures when the chip driver invokes the controller driver write() function passing a 256 byte page: only 64 bytes get written. This problem is not easy to fix in u-boot, this change suggests a scheme to allow the size override for certain SPI controllers. BUG=chromium-os:20105 TEST=manual . this change was tested combined with other modification, the ability to read and save the 16KB environment in a maconix SPI flash was demonstrated.

2011-08-29Modify the API for doing transfers over SPI.Gabe Black
This change modifies the spi_xfer function to take read and write buffers and read and write bit counts which is similar to what flashrom does. This has the nice effect of simiplifying many call sights, and will allow integrating SPI controllers which don't allow arbitrary control of the chip select lines. Only boards which are being used with ChromeOS and the functionality they use will be updated immediately. That's because those are the cases which can actually be tested effectively, and fixing up the other locations can be put off until later. These change and the eventual change that updates all the other call sights/drivers can also be reviewed and tested independently. It will also make rebasing easier. To try to make the transition less painful, the new interface is selectable using the CONFIG_NEW_SPI_XFER option. This selects whether the new or old interface is used. BUG=chrome-os-partner:4722 TEST=With this and related changes, built for x86-alex, tegra2_kaen, tegra2_aebl, tegra2_seaboard, and tegra2_asymptote.

All ONFI revisions should be backwards-compatible; even if this is not the case on some newer ONFI revision, it should simply fail the second version-checking if-else block (i.e., the bit-fields for 1.0, 2.0, etc. would not be set to 1). Thus, we move our "unsupported" condition after having checked each bit field. Also, it's simple enough to add a condition for ONFI revision 2.3. Note that this does *NOT* mean we handle all new features of ONFI versions above 1.0.
