****************************************************************************
*  History:
*
*  14.12.02  mifi   First Version 
*  18.01.03  mifi   Change Licence from GPL to BSD
*  25.01.03  mifi   Change FAT32Init 
*                   New function FAT32MountDrive and FAT32UnMountDrive
*                   Remove FAT32_MAX_FILES, a file handle will be 
*                   allocated by NutHeapAlloc, therefore we have no
*                   restrictions about the count of the open file handle.
*                   (Only by available memory)
*  27.01.03  mifi   Rename all FAT32xxx function to FATxxx.
*
*  28.01.03  mifi   Start porting to Nut/OS 3.X.X
*  29.06.03  mifi   First ATAPI-Version
*  24.07.04  mifi   Some changes to support more than one drive (datanut)
*  25.07.04  mifi   Add support for the PCMCIA_11 hardware.
*  27.07.04  mifi   Add support for IOCTL function
