Add the option to load the bootscript with the tftp command (static IP) instead of the dhcp command (dynamic IP). For this a new function tftpb_run similar to dhcp_run, is needed. The selection of which command to use can be done with the ip_dyn environment variable, which can be set to yes or no. The ip_dyn variable was chosen as it is already in use on the imx platforms. Also edit the bootstd doc. Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Benjamin Hahn <B.Hahn@phytec.de>
