2013-06-23sf: Add flag status register polling supportJagannadha Sutradharudu Teki
Flag status register polling is required for micron 512Mb flash devices onwards, for performing erase/program operations. Like polling for WIP(Write-In-Progress) bit in read status register, spi_flash_cmd_wait_ready will poll for PEC(Program-Erase-Control) bit in flag status register.

2013-03-19sf: Use spi_flash_alloc() in each SPI flash driverSimon Glass
Rather than each device having its own way to allocate a SPI flash structure, use the new allocation function everywhere. This will make it easier to extend the interface without breaking devices. Signed-off-by: Simon Glass <sjg@chromium.org>

2012-08-09sf: stmicro: add support N25Q128 partsStephan Linz
Adds support for Numonyx's N25Q128 SPI flash. These devices are used on (among others) Avnet Spartan-6 LX9 micro-evaluation boards. Tested with "sf" commands and CONFIG_ENV_IS_IN_SPI_FLASH. Signed-off-by: Stephan Linz <linz@li-pro.net> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-08-09sf: stmicro: support JEDEC standard two-byte signatureStephan Linz
There are more than the M25Pxx serial flashs that can be used with the stmicro driver, for example: the M25PXxx or N25Qxx serie. All these chips have burned in the original stmicro manufacture id 0x20 together with a standard two-byte signature. In preperation to support all these chips the stmicro driver have to decode the full two-byte signature.

2012-04-08sf: stmicro: add geometrical info for N25Q256 from MicronJérôme Carretero
Note: because 4-byte addressing is not supported yet, at the moment only the first 16MiB of the device are available. Signed-off-by: Jérôme Carretero <cJ@zougloub.eu> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-03-04sf: unify erase commandsMike Frysinger
Analysis of the flash drivers shows that they all use 0x20 if the erase size is 4KiB, or 0xd8 if it's larger. So with this info in hand, we can unify all the erase functionality in one place. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-03-04sf: inline data constantsMike Frysinger
I imagine much of these constants are due to copy & pasting previous drivers rather than an actual reflection of the hardware layout. At any rate, inline the info that we don't care about externally as it shrinks things nicely. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-07-20sf: drop unused/duplicate command definesMike Frysinger
In an effort to unify the spi flash drivers further, drop all the unused and/or duplicate command defines. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-26sf: eon/stmicro: inline useless ID definesMike Frysinger
These defines are used in only one place, so just inline them. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-26sf: kill off now-unused local stateMike Frysinger
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>
2011-07-26sf: unify write funcsMike Frysinger
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>
2011-07-26sf: unify write enable commandsMike Frysinger
Every spi flash uses the same write enable command, so unify this in the common code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-04-12sf: localize erase funcsMike Frysinger
No need for these to be exported as they are only accessed indirectly via function pointers. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-04-12sf: add struct spi_flash.sector_size parameterRichard Retanubun
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).

2011-04-11sf: unify status polling for ready bitMike Frysinger
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>
2010-06-30sf: move useful messages from debug to printfMike Frysinger
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>
2010-06-30spi_flash: support old STMicro parts with RESThomas Chou
Some old STMicro parts do not support JEDEC ID (0x9f). This patch uses RES (0xab) to get Electronic ID and translates it to JEDEC ID. Signed-off-by: Thomas Chou <thomas@wytron.com.tw> Acked-by: Mike Frysinger <vapier@gentoo.org>

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: 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
The stmicro_wait_ready() func tries to show the actual opcode that was sent to the device, but instead it displays the array pointer. Fix it to pull out the opcode from the start of the array. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
