[yocto] Kernel does not emit any boot-up messages

[Hartmut Behrens]

Hi All,

A newbie question:

After creating a new bsp for an Overo using the yocto-bsp script and
modifying some kernel config's using menuconfig, I successfully created and
loaded the image (core-image-minimal) onto an SD card and booted it.

However, I do not see the kernel emitting any boot messages. Am I
forgetting to include some recipes?
