U-boot issues on Banana Pi M2

[Emmanuel Vadot]

 Hello Erik,

 I can reproduce the issue, until I fix it can you test reverting the
last update of sysutils/u-boot-olimex-a20-som-evb (this is the master
port that u-boot-bananapim2 is using) ? Switching back to 2016.05
worked for me.
 I'll try to find some times this weekend to fix this.

 Thanks,
