Your LP report states that the ehci/musb port is not setup due to
misconfiguration, yet all relevant config options are defined as
modules. Can you go into a bit more depth as to why they have to be
built-in as opposed to being modules?

Hi Tim,

Sure, and i can edit the commit to add more information.

Basically, as the config currently is, neither my beagle Bx & C4 will
register a usb subsystem (via lsusb).

This also fixes the use case where a user:

Has a kernel in Nand or on the SD card and has the rootfs on an
external usb drive.

Regards,

if you boot without initramfs or only with a bare kernel (only using
vmlinuz/uImage but not the /lib/modules dir due to not having the
package installed in the rootfs), you might need to have them built in.

indeed thats a corner case given that ubuntu default images will use
initramfs and have the modules available early enough but imho a valid
request.

Amit informs me that OMAP will eventually have an initramfs, which ought
to cover the case for modular boot essential drivers. I'll leave it up
to him to decide what to do in the meantime.
