* $Log: V:/Flite/archives/TrueFFS5/Src/NANDDEFS.H_V $ * * Rev 1.9 Apr 15 2002 07:38:10 oris * Added 2 additional fields to mtdVars record for backwards compatibility (under RAM_MTD compilation flag) * - unsigned short pageSize; * - unsigned short pageAndTailSize; * * Rev 1.8 Jan 20 2002 20:29:14 oris * Changed doc2000FreeWindow prototype to remove warnings. * Changed docPlusFreeWindow prototype to remove warnings. * * Rev 1.7 Jan 17 2002 23:03:52 oris * Definitions for the new memory access routine mechanism * - NDOC2window was moved from docsys.h * - Add pointer to read back buffer when MTD_RECONSTRUCT_BBT and VERIFY_VOLUME compilation flags are defined. * Replaced flbuffer.h include with flflash.h * Changed win_io from unsigned to word. * Changed the use of vol (macro *pVol) to *flash in NFDC21thisVars. * * Rev 1.6 Sep 15 2001 23:47:50 oris * Added 128MB flash support * * Rev 1.5 Jul 13 2001 01:08:58 oris * Added readBackBuffer pointer for the VERIFY_WRITE Compilation flag. * * Rev 1.4 May 16 2001 21:21:14 oris * Change "data" named variables to flData to avoid name clashes. * * Rev 1.3 Apr 10 2001 16:43:40 oris * Added prototype of docSocketInit. * * Rev 1.2 Apr 01 2001 07:48:26 oris * Revised in order to support both diskonchip 2000 family and doc plus family. * * Rev 1.1 Feb 07 2001 17:42:24 oris * removed MAX_FLASH_DEVICES_MDOC define since alone can support 16 chips * * Rev 1.0 Feb 04 2001 12:26:10 oris * Initial revision. * */
