I agree.  But when you responded, you responded just to me, not the mailing
list.  I was replying to you as you wrote to me.  Please re-check your
email.

While that option is not in u-boot directly, it seems like it wouldn't be
that big of a deal since u-boot can read from the dataflash.  It will just
check the first 6 instructions for an arm instruction as I understand it so
you could easily move that code from boot.bin into u-boot and save the two
stage process.
