Hi Gary,

How are you?

Now it's my turn to apologize for the very late answer; I am sorry.

About pushing to upstream u-boot; I am a bit reluctant to push this
patch to upstream u-boot because I think that booting to the /init
wrapper when using a ramdisk is a buildroot specificity (from fs/cpio/init).
  I certainly would not like to break the default behavior in upstream
u-boot, even in mfgtools mode, which is to call /linuxrc right now.

You are also right that the same functionality can be obtained from the
u-boot command line, but that means a user interaction. The goal of
adding this u-boot patch at buildroot level is to allow a
fully-automated boot of a buildroot filesystem through USB without user
  (See [1] for more details on the whole procedure.)

What is your opinion on that, please?

Also, now that I have been very slow to answer to your e-mail, a nice
patches series from Luca has been around [2], which renames the config file.
  After a quick try, rebasing with git seems to be free, but do you
prefer that I send a v2 rebased on those, just in case?

Best regards,
