Thanks!
 
Well, it's related to those problems:
 
http://forum.armbian.com/index.php/topic/691-banana-pro-testers-wanted-sata-drive-not-working-on-some-boards/
I simply revert my changes (have one config for all Bananas) back to kernel default until I get Banana PRO on my desk and do all tests.
 
Now you need to manually select:
 
sun7i-a20-bananapi-m1-plus.dtb
sun7i-a20-bananapro.dtb
 
in boot.cmd.
 
1. Edit /boot/boot.cmd
2. Replace /boot/dtb/${fdtfile} with /boot/dtb/sun7i-a20-bananapro.dtb or sun7i-a20-bananapi-m1-plus.dtb
3. Save and recompile: mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr
4. Reboot
 
 
 
That's ok - I don't rebuild images for every change since we achieve the same with apt-get upgrade.

Wifi is working now...
 
I used following commands on my BananaPro board with legacy kernel and Ubuntu Trusty:
( Download link of used system image http://mirror.igorpecovnik.com/Armbian_4.5_Bananapi_Ubuntu_trusty_3.4.109_desktop.zip.
Note: If this link should be different for BananaPi and for BananaPro it is not my fault :-) )
 
# based on previous posts I decided return back old kernel version 3.4.109 for bananapi because wifi driver is not working on latest kernel supplied with system image
apt-get purge linux-firmware-image-sun7i -y
rm /etc/modules -Rv # apt-get cannot remove this folder during uninstall procedure # removed 20.1.
rm /lib/firmware -Rv # apt-get cannot remove this folder during uninstall procedure # added 20.1.
aptitude install linux-image-banana linux-headers-banana linux-firmware-image-banana linux-u-boot-bananapi -y
 
rm -v /boot/script.bin
ln -vs /boot/bin/bananapipro.bin /boot/script.bin
 
echo ap6210 >> /etc/modules && cat /etc/modules
 
# generate encrypted wifi password and copy output to clipboard
wpa_passphrase yourSSID yourpassword
# edit /etc/network/interfaces
# remove "#" symbol like you can see in example below
# replace "yourSSID" and "yourpassword" with your wifi SSID and ecrypted password
nano /etc/network/interfaces
 
EXAMPLE:
# Wired adapter #1
auto eth0
        iface eth0 inet dhcp
#       hwaddress ether # if you want to set MAC manually
#       pre-up /sbin/ifconfig eth0 mtu 3838 # setting MTU for DHCP, static just: mtu 3838
#
# Wired adapter #2
#auto eth1
#       iface eth1 inet dhcp
#       hwaddress ether # if you want to set MAC manually
#       pre-up /sbin/ifconfig eth0 mtu 3838 # setting MTU for DHCP, static just: mtu 3838
#
# Wireless adapter #1
auto wlan0
        allow-hotplug wlan0
        wpa-ssid yourSSID
        wpa-psk yourpassword
# to generate proper encrypted key: wpa_passphrase yourSSID yourpassword
#
# Local loopback
auto lo
        iface lo inet loopback
 
AND REBOOT and it should work like in my case ;-)
