[coreboot] buildrom: optional delay to kexec fails

[Andreas B. Mundt]

Hi everybody,

in revision 125 of buildrom an optional delay before the LAB
environment kexecs the on-disk kernel has been introduced. For me this
does not work. There is neither a delay nor can I enter the busybox
environment by pressing return. After showing the
delay-press-key-message, the on-disk kernel is booted
immediately. I use a 64 bit kernel in LAB. (The default one with amd64
configuration.) What can go wrong?

Regards,

	Andi
