I don't see the (required) "-a" and "-e"  options  in  your  call  to
mkimage...

Like this? What is "this"? You don't shouw us which exact boot
commands you used, nor what your environment settings are.

How are we supposed to help you without all this important information?

^^^^^^^^^^^^^^^^^^^^^^^^^^^

Where is this coming from?

verification - which will take a looong time on an uncompressed kernel
image. See "verify" environment variable.

No, it is not.

See above.
