- * Support for persistent environment data
- *
- * The "environment" is stored on external storage as a list of '\0'
- * terminated "name=value" strings. The end of the list is marked by
- * a double '\0'. The environment is preceeded by a 32 bit CRC over
- * the data part and, in case of redundant environment, a byte of
- * flags.
- *
- * This linearized representation will also be used before
- * relocation, i. e. as long as we don't have a full C runtime
- * environment. After that, we use a hash table.

- *		will be added (which is included in the "filesize"
- *		setting so you can for exmple copy this to flash and

- *	-b:	export as binary format (name=value pairs separated by
- *		'\0', list end marked by double "\0\0")
- *	-c:	export as checksum protected environment format as
- *		used for example by "saveenv" command
- *	-s size:
- *		size of output buffer
- *	addr:	memory address where environment gets stored
- *	var...	List of variable names that get included into the
- *		export. Without arguments, the whole environment gets
- *		exported.
- *
- * With "-c" and size is NOT given, then the export command will
- * format the data as currently used for the persistent storage,
- * i. e. it will use CONFIG_ENV_SECT_SIZE as output block size and
- * prepend a valid CRC32 checksum and, in case of resundant
- * environment, a "current" redundancy flag. If size is given, this
- * value will be used instead of CONFIG_ENV_SECT_SIZE; again, CRC32
- * checksum and redundancy flag will be inserted.
- *
- * With "-b" and "-t", always only the real data (including a
- * terminating '\0' byte) will be written; here the optional size
- * argument will be used to make sure not to overflow the user
- * provided buffer; the command will abort if the size is not
- * sufficient. Any remainign space will be '\0' padded.
- *
- * On successful return, the variable "filesize" will be set.
- * Note that filesize includes the trailing/terminating '\0' byte(s).
- *
- * Usage szenario:  create a text snapshot/backup of the current settings:
- *
- *	=> env export -t 100000
- *	=> era ${backup_addr} +${filesize}
- *	=> cp.b 100000 ${backup_addr} ${filesize}
- *
- * Re-import this snapshot, deleting all other settings:
