[yocto] trouble building bsp for arm

[Dallas Clement]

Hi all,  Please bear with me as I am a newb to both yocto and building
bsp's.   I was able to run bitbake core-image-minimal for x86-64, just fine and
run it in qemu.

Then I got gutsy and tried to build a bsp for ARM.  Didn't go so well.
 I must be missing something.

dallasc ~/development/yocto/poky-denzil-7.0] scripts/yocto-bsp create
marvell-armada-xp-mv78260 qemu
Which qemu architecture would you like to use? [default: i386]
       1) i386    (32-bit)
       2) x86_64  (64-bit)
       3) ARM     (32-bit)
       4) PowerPC (32-bit)
       5) MIPS    (32-bit)
3
Would you like to use the default (3.2) kernel? (y/n) [default: y]
Do you need a new machine branch for this BSP (the alternative is to
re-use an existing branch)? [y/n] [default: y]
Getting branches from remote repo None...

Can anyone recommend what I should do to get past this?

Thanks,
