Hmm. I take that back. Patch 4 causes a problem, at least when
applied
on top of u-boot/master from today.
Basic serial output works just fine, and I can interact with U-Boot without issue. However, when the boot scripts execute and load an extlinux.conf, U-Boot hangs. Up to patch 3, everything is fine.
U-Boot 2014.10-00004-g7830ed7 (Oct 17 2014 - 20:47:19)
DRAM: 480 MiB WARNING: Caches not enabled MMC: bcm2835_sdhci: 0 Using default environment

Can you please point me to where I can get an image to try this with? Also did you check with dm/next? There may be dependent patches, although the nature of the problem suggests not.
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?
Regards, Simon
