2013-05-24sf: spansion: Add support for S25FL128SXie Xiaobo
SPANSION recommend S25FL128S supersedes S25FL129P, and the two flash memory have the same device ID and Memory architecture. So they can use the same config parameters. Signed-off-by: Xie Xiaobo <X.Xie@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

2013-03-19sf: Enable FDT-based configuration and memory mappingSimon Glass
Enable device tree control of SPI flash, and use this to implement memory-mapped SPI flash, which is supported on Intel chips. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-19sf: Respect maximum SPI write sizeSimon Glass
Some SPI flash controllers (e.g. Intel ICH) have a limit on the number of bytes that can be in a write transaction. Support this by breaking the writes into multiple transactions. Signed-off-by: Simon Glass <sjg@chromium.org>
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>
2013-03-19sf: Add spi_flash_alloc() to create a new SPI flash structSimon Glass
At present it is difficult to extend the SPI flash structure since all devices allocate it themselves, and few of them zero all fields. Add a new function spi_flash_alloc() which can be used by SPI devices to perform this allocation, and thus ensure that all devices can better cope with SPI structure changes.

2012-08-14sf: winbond: fix page_sizeStephen Warren
Commit a4ed3b6 "sf: inline data constants" modified winbond.c's page_size from 256 to 4096. This prevents either/both of "sf write" writing the correct data, or "sf read" from reading the correct data back. This allows U-Boot running on Compulab Tegra to upgrade itself.

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.

2012-03-04sf: unify status register writing (and thus block unlocking)Mike Frysinger
The only two drivers to write the status register do it in the same way, so unify the implementations. This also makes the block unlock logic the same. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-03-04sf: sst: inline duplicate write enable helper funcsMike Frysinger
The local sst enable/disable write funcs don't really add anything over the common API, so just inline the common calls directly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Looks like Shaohui Xie's patch got merged twice. 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>

2011-07-26sf: sst: support newer standardized flashesMike Frysinger
Newer SST flashes have dropped the Auto Address Increment (AAI) word programming (WP) modes in favor of the standard page programming mode that most flashes now support. So add a flags field to the different flashes to support both modes with new and old styles. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
