mtd/include/mtd mtd-abi.h,1.9,1.10

[Andrew Victor]

Update of /home/cvs/mtd/include/mtd
In directory phoenix.infradead.org:/tmp/cvs-serv26392/include/mtd

Modified Files:
	mtd-abi.h 
Log Message:
Adds support for JFFS2-on-Dataflash devices.

For Dataflash, can_mark_obsolete = false and the NAND write buffering
code (wbuf.c) is used.

Since the DataFlash chip will automatically erase pages when writing,
the cleanmarkers are not needed - so cleanmarker_oob = false and
cleanmarker_size = 0

DataFlash page-sizes are not a power of two (they're multiples of 528
bytes).  The SECTOR_ADDR macro (added in the previous core patch) is
replaced with a (slower) div/mod version if CONFIG_JFFS2_FS_DATAFLASH is
selected.
