Dear Wolfgang,
You will find attached a patch that add the support of the dos diskette. It adds commands to boot a file from a dos diskette or from a subdirectory of a dos diskette and to list content from dos diskette.
fdosboot [offset] [filename]: boot a file from a dos diskette or from a subdirectory of the diskette. If the offset isn't specified, the file name must start wit the character " (as for the tftpboot command). The path of the filename is specified using the / as separator between directorie names.
fdosls [dir]: list the content of the dos diskette or of a subdirectory.
These two commands are embedded into U-Boot if CFG_CMD_FDOS is defined in CONFIG_COMMANDS.
The handling of the dos filesystem is inspired from mtools.
CHANGELOG: * Patch by Pierre Aubert , 12 Nov 2002 Add support of dos diskettes.
Best regards.
