S5PV210 boot problem

[Nasser]

Dear friends, I have problem booting my custom HW (around s5pv210 SoC) 
using the latest stable kernel release (v4.8.5). Of course this is the first DT
based kernel I'm trying to boot with in this HW. I chose s5pv210_defconfig and 
by checking CONFIG_ARM_APPENDED_DTB, appended the DTB (s5pv210-smdkv210.dtb) at the end of zImage.

The boot loader is based on the old u-boot v1.3.4.
Due to some problems with kernel decompression, I revert 
1fdc08abfa26f30fcef0ce1333e9ac6f80350f30 ARM: decompressor: avoid speculative prefetch from non-RAM areas 
for a successful boot on every new kernel and it worked till now (for non-DT
kernels)

Boot log messages is attached. There are some problems with clock
settings and obviously "Division by zero in kernel".
Can anybody shed some light on the possible issue(s)?
