* sf: winbond: Add support for the Winbond W25X40James Le Cuirot2011-09-05-0/+8
| | | | | The Winbond W25X40 is now being used in the IP02 (and possibly IP04). Tested and working on the actual device.
* sf: kill off now-unused local stateMike Frysinger2011-07-26-26/+13
| | | | | | | | Now that the common spi_flash structure tracks all the info that these drivers need, kill off their local state indirection and use just what the common code provides. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* sf: unify write funcsMike Frysinger2011-07-26-68/+3
| | | | | | | Once we add a new page_size field for write lengths, we can unify the write methods for most of the spi flash drivers. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* sf: unify write enable commandsMike Frysinger2011-07-26-1/+1
| | | | | | | Every spi flash uses the same write enable command, so unify this in the common code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* sf: localize erase funcsMike Frysinger2011-04-12-1/+1
| | | | | | | No need for these to be exported as they are only accessed indirectly via function pointers. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* sf: add struct spi_flash.sector_size parameterRichard Retanubun2011-04-12-8/+3
| | | | | | | | | | | | | | | This patch adds a new member to struct spi_flash (u16 sector_size) and updates the spi flash drivers to start populating it. This parameter can be used by spi flash commands that need to round up units of operation to the flash's sector_size. Having this number in one place also allows duplicated code to be further collapsed into one common location (such as erase parameter and the detected message).

* sf: unify status polling for ready bitMike Frysinger2011-04-11-47/+4
| | | | | | | | All of the spi flash drivers implement the status register polling for detecting the device ready state, so unify them all in a new helper function -- spi_flash_wait_ready. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* sf: winbond: add support for W25Q16/32/128 partsWojtek Skulski2010-12-17-10/+29
| | | | | | | While we're here, cut out the useless id defines too. Signed-off-by: Wojtek Skulski <skulski@pas.rochester.edu> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* sf: winbond: add support W25Q64 partsGraeme Smecher2010-10-06-0/+9
| | | | | | | | | Adds support for Winbond's W25Q64 SPI flash. These devices are used on (among others) Xilinx' SP601 and SP605 Spartan-6 evaluation boards. Tested with "sf" commands. Signed-off-by: Graeme Smecher <graeme.smecher@mail.mcgill.ca> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* sf: move useful messages from debug to printfMike Frysinger2010-06-30-3/+4
| | | | | | | | | | At the moment, the default SPI flash subsystem is quite terse. Errors and successes both result in a generic message. So move the useful errors and useful successes to printf output by default. While we're here, also convert the messages to use print_size(). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
