Dear ARM guys,
I am HuangZhaoyang who is assignee engineer of linaro. I would like
raise one problem which I find on juno board. Please help to check it
when convenient. That is,
The upstreaming kernel(v4.1 form torvalds's tree) can not boot up on
juno. The terminal show bellowing logs and hung up then.

Shell> Image dtb=juno/juno.dtb console=ttyAMA0,115200 rootwait
root=/dev/sda2

Please use the upstream dtb if you are not already. The downstream
kernel once carried a hack for memory mapped timer and had it enabled in
DT. However the upstream DTB doesn't enable the broken timer and it
should resolve your boot issue.
