pxe: fix handling of different localboot values
Add support for value of -1 For localboot. A value of -1 means return to u-boot prompt. The localboot value is often 0, so we need to distinguish the value from localboot being selected. A value of greater than or equal to 0 means attempt local boot command. If localboot is selected, we don't want to try other entries. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
