Wow, that's a big leap...

You should also consider to update to the latest version of U-Boot;
the time when it was still called PPCBoot is long, long past.

You loaded the image at 01900000, but the uncompr4essed image extends
until 02f58efc, i. e. there is a good chance that you will overwrite
parts of the still uncompressed image.

Your device tree might be wrong, too.
