- assume wbuf may be of size which is not power of 2 - don't make strange assumption about not padding wbuf for DataFlash - use wbuf = DataFlash page and eraseblock >= 8 Dataflash pages From: Peter Menzebach <pm-mtd@mw-itcon.de> Acked-by:

Always keep valid data in reserved_size. It did not cause problems, but the reservation code was unoptimal when centralized summary was active or the size of the erase block was very small. Signed-off-by:

The changes introduced allow to suspend/resume NAND flash. A new state (FL_PM_SUSPENDED) is introduced, as well as routines for mtd->suspend and mtd->resume to put the flash in suspended state from software pov. Signed-off-by:

Do the summary collection in the right place. If the device was not writebuffered but had c->mtd->writev function (e.g. blkmtd) the summary collector function was not called. Signed-off-by:

- Intel chip driver has a reboot notifier so no need to reset the chip here. - Don't play with chip selects (platform code should do this if necessary). Signed-off-by:

The goal of summary is to speed up the mount time. Erase block summary (EBS) stores summary information at the end of every (closed) erase block. It is no longer necessary to scan all nodes separetly (and read all pages of them) just read this "small" summary, where every information is stored which is needed at mount time. This summary information is stored in a JFFS2_FEATURE_RWCOMPAT_DELETE. During the mount process if there is no summary info the orignal scan process will be executed. EBS works with NAND and NOR flashes, too. There is a user space tool called sumtool to generate this summary information for a JFFS2 image. Signed-off-by:

While this might be useful for all supported flash types, it is mandatory for proper JFFS2 support with Sibley flash. Signed-off-by:

Nicolas Pitre authored
This updates the Primary Vendor-Specific Extended Query parsing to version 1.4 in order to get the information about the Configurable Programming Mode regions implemented in the Sibley flash, as well as selecting the appropriate write command code. This flash does not behave like traditional NOR flash when writing data. While mtdblock should just work, further changes are needed for JFFS2 use. Signed-off-by:
