help
This option allows you to use a so-called USB EHCI Debug device
to retrieve the coreboot debug messages (instead, or in addition
to, a serial port).
This feature is NOT supported on all chipsets in coreboot!
It also requires a USB2 controller which supports the EHCI
Debug Port capability. Controllers which are known to work:
* 10b9:5239 ALi Corporation USB 2.0 (USB PCI card)
* 8086:24cd Intel ICH4/ICH4-M
* 8086:24dd Intel ICH5
* 8086:265c Intel ICH6
* 8086:268c Intel 631xESB/632xESB/3100
* 8086:27cc Intel ICH7
* 8086:2836 Intel ICH8
* 8086:283a Intel ICH8
* 8086:293a Intel ICH9
* 10de:0088 NVIDIA MCP2A
* 10de:005b NVIDIA CK804
