I just built Yocto/Poky for the raspberrypi, following the
recent thread on this list.  I noticed that the resulting SD
image is ~4GB, but most of that space seems to be unused:

  $ ssh root@192.168.1.150

   179        2    3885056 mmcblk0p2

Notice that the physical partition for /dev/mmcblk0p2 is huge but
the file system is only 57MB.

How can I adjust my build and/or resize the file system to actually
use the rest of the SD card?

Also, is it possible to just build the SD image much like I do for
other devices like the BeagleBoard, albeit with different contents
in /boot?  Sloshing around 4GB images is rather painful, plus it
takes forever to DD it to the SD card.

Thanks
