Hello
An user reported on IRC that he get two OrangePi PC with the same MAC address
with uboot 2016.05 and sun8i-emac v4.
Giving the following MAC address 02:20:08:00:00:00
He dumped the two SID using devmem2:
2004620 34344314 503A04CE 800
2004620 34344314 503B0C0E 800
According to board/sunxi/board.c, the MAC address is generated from sid[0] and
sid[3]
According to http://linux-sunxi.org/SID_Register_Guide, it seems that only
sid[2] is always different.
So probably the MAC address generation should be modified.
It is strange that the board didnt get the CRC32 of sid[3], but the problem
would remain the same.

U-Boot v2016.05 doesn't yet contain the change that improved on MAC
generation by using the CRC32 of all SIDs.
The corresponding http://git.denx.de/?p=u-boot.git;a=commit;h=3f8ea3b0
only made it into v2016.09 and later.
