In directory phoenix.infradead.org:/tmp/cvs-serv5884/include/linux/mtd

Modified Files:
	nand.h 
Log Message:
[MTD] NAND: do not write the whole page in nand_write_oob by default

Added NAND_COMPLEX_OOB_WRITE option that specifies if a whole NAND page is 
to be written in nand_write_oob routine. This may be necessary for some HW 
ECC generators that need a whole page to be written to generate ECC properly.
This option is to be set by NAND chip driver. it's not set by default.
Accordingly, nand_write_oob was modified to not write the whole page is
NAND_COMPLEX_OOB_WRITE option is not set.
