* $Log: V:/Flite/archives/TrueFFS5/Src/DOCSYS.H_V $
|
||
|
|
*
|
||
|
|
* Rev 1.12 Apr 15 2002 07:36:04 oris
|
||
|
|
* Reorganized for final release.
|
||
|
|
*
|
||
|
|
* Rev 1.11 Feb 19 2002 20:59:04 oris
|
||
|
|
* Removed flflash.h include directive.
|
||
|
|
*
|
||
|
|
* Rev 1.10 Jan 28 2002 21:24:20 oris
|
||
|
|
* Removed the use of back-slashes in macro definitions.
|
||
|
|
* Replaced FLFlash argument with DiskOnChip memory base pointer.
|
||
|
|
* Changed interface of write and set routines (those that handle more then 8/16 bits) so that instead of FLFlash record they receive the DiskOnChip memory window base pointer and offset (2 separated arguments). The previous implementation did not support address
|
||
|
|
* shifting properly.
|
||
|
|
* Changed memWinowSize to memWindowSize
|
||
|
|
* Removed FL_ACCESS_NO_STRING.
|
||
|
|
*
|
||
|
|
* Rev 1.9 Jan 17 2002 22:59:46 oris
|
||
|
|
* Completely revised, to support runtime customization and all M-Systems
|
||
|
|
* DiskOnChip devices
|
||
|
|
*
|
||
|
|
* Rev 1.8 Nov 16 2001 00:19:58 oris
|
||
|
|
* Added new line in the end, to remove warning.
|
||
|
|
*
|
||
|
|
* Rev 1.7 Sep 25 2001 15:35:04 oris
|
||
|
|
* Restored to OSAK 4.3 implementation.
