   3 # This is a simple script which helps you to boot the linux kernel
   4 # on a Zynq board by using uImage and loading the linux kernel via
   5 # TFTP.
   6 # If you call it the first time you have to specify a uImage (the
   7 # linux kernel), a compiled device tree blob, the ps7_init.tcl
   8 # script and a u-boot executable.
   9 # The last used files are cached by the script and can be reused
  10 # the next time by calling the script with no parameters. This
  11 # makes it easy to use because during the development cycle the
  12 # needed files does not change very often.
