[U-Boot] Upstream uboot and Arndale 5250 support

[Paolo Pisati <p.pisati@gmail.com>]

Hi,

i've been trying to update the u-boot on my board (sd booting), from the Linaro
one (2012.10) to a v2014.X, but so far had no luck:

make arndale_config
export CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf-
make

...

dd if=arndale-bl1.bin of=/dev/sdc bs=512 skip=1
dd if=arndale-spl.bin of=/dev/sdc bs=512 skip=17
dd if=./u-boot-dtb.bin of=/dev/sdc bs=512 skip=49

...

u-boot 3.10rc3 (same happens with v2014.07 or 2014.04):

Any idea what's going wrong? Did you try this board lately?

It's a kernel with the DTB concatenated (and it works fine with Linaro 2012
uboot), but the same happens if i explicitely pass the dtb:
