* Update TRAB auto update code

* Make fatload set filesize environment variable
  fix potential buffer overlow problem

* enable basic / medium / high-end configurations for PPChameleonEVB
  board; fix NAND code

* enable TFTP client code to specify to the server the desired
  timeout value (see RFC-2349)
