Add a kconfig option to allow the user to select a specific physical
USB port for use as Debug Port (on chipsets which support that). Signed-off-by: Uwe Hermann <uwe@hermann-uwe.de> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5860 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1

+ This option selects which physical USB port coreboot will try to
+ use as EHCI Debug Port first (valid values are: 1-15).
+
+ If coreboot doesn't detect an EHCI Debug Port dongle on this port,
+ it will try all the other ports one after the other. This will take
+ a few seconds of time though, and thus slow down the booting process.
+
+ Hence, if you select the correct port here, you can speed up
+ your boot time. Which USB port number (1-15) refers to which
+ actual port on your mainboard (potentially also USB pin headers
+ on your mainboard) is highly board-specific, and you'll likely
+ have to find out by trial-and-error.
