  i'll get a chance to test the above this weekend, but i just want to
make absolutely sure we're talking about the same thing. are you
saying that with the above patches, the u-boot-tools will be able to
manipulate an eMMC HW partition just as easily as a regular MTD
partition? and, if so, what is the format of the entry one would add
to /etc/fw_env.config to refer to that eMMC HW partition (in this
case, boot1)?

  thanks.
