This can be useful to force bootcmd to execute as soon as U-Boot has started.
My use-case is: An SoC-specific tool pushes U-Boot into RAM, along with an image to be written to device boot flash, with the DT config property "bootcmd" set to contain a command to write that image to flash. In this scenario, we don't want to allow any stale bootdelay value taken from the current flash content to affect how long it takes before the flashing process starts.
