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 8000000
2004620 34344314 503B0C0E 8000000
According to board/sunxi/board.c, the MAC address is generated from sid and
According to http://linux-sunxi.org/SID_Register_Guide, it seems that only
sid is always different.
So probably the MAC address generation should be modified.
It is strange that the board didnt get the CRC32 of sid, 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.
