help Obtain help for CFE commands

For more information about a command, enter 'help command-name'
*** command status = 0
CFE> e
'e b' to reinitialize NAND flash or 'e a' to erase kernel
*** command status = 0
CFE> e b
Reinitialize NAND flash? (y/n):y

Now think carefully. Do you really,
really want to reinitialize the NAND flash? (y/n):y
Initializing GOOD BLOCKS only.
