I use (a pretty old version of, but I doubt that matters) RPi Foundation's Raspbian image, and compiled the kernel and U-Boot according to:
http://elinux.org/index.php?title=RPi_Upstream_Kernel_Compilation&oldid=...
I installed the Raspbian image but I don't get uImg.txt nor the same boot sequence. I am able to boot a kernel though.
Do you have your settings or images uploaded somewhere? Also please confirm you used dm/next.
FWIW, the content in the following branches does seem to work:
u-boot/master 5b3ee38 kbuild: clear VENDOR variable to fix build error on tcsh
u-boot-dm/master c2ded96 serial: remove uniphier_serial_initialize() call
In what way?
I ran U-Boot, and let it boot a kernel via extlinux.conf.
Ok that is probably just because I didn't pull in the patch you said was a problem.
Note that I said it worked, not that it failed.
I did misread this...
