No, none thaty I am aware of.

Note that usually this makes little sense.  Using a compressed U-Boot
image can have two effects:

- saving some memory on the boot device; usually reacent hardware has
  ample resources, so saving 100...200 kB is typically not important
  enough to add such complexity.
- saving time when loading the U-Boot image from the boot device *at
  the cost of adding time needed to uncompress it).  If you ant to
  reduce boot time, it is more efficient to use Falcon mode and skip
  loading U-Boot completely when running in production mode.

So there is actually little motivation to implement such a feature -
but your milage may vary, or you may have specific requrements where
it actually makes sense.

Patches welcome.

Best regards,

Wolfgang Denk
