  *  08-17-2002	tglx: fixed signed/unsigned missmatch in write.c
  *		Thanks to Ken Offer <koffer at arlut.utexas.edu> 	
  *
+ *  08-29-2002  tglx: use buffered read/write only for non pagealigned 
+ *		access, speed up the aligned path by using the fs-buffer
+ *		reset chip removed from nand_select(), implicit done
+ *		only, when erase is interrupted
+ *		waitfuntion use yield, instead of schedule_timeout
+ *		support for 6byte/512byte hardware ECC
+ *		read_ecc, write_ecc extended for different oob-layout
+ *		selections: Implemented NAND_NONE_OOB, NAND_JFFS2_OOB,
