Interesting. So with this in mind, would it be acceptable to assume that
BOOT_DEVICE_USB and BOOT_DEVICE_USBETH are always two distinct boot
devices and thus not have to care about whether they're equal or not and
just assume they're not, like any other BOOT_DEVICE?
This would greatly simplify the logic and make everything more readable.
I can submit a new patch set in that direction tomorrow.
