Bug#911560: possible fix / workaround

["Andreas B. Mundt" <andi@debian.org>]

Control: tags -1 patch


Hi all,

I tried to boot a 'Olimex A20 Lime 2 Rev. K' too, and as reported, the
ethernet PHY seems not to be initialized well and fails to work at all. 

Following the advice of the sunxi wiki [1], recompiling u-boot with
the proposed patch [2] fixed this:  Ethernet works in u-boot as well
as in the installer with the patched u-boot. 

No idea if this patch spoils the other revisions.

Best regards,

  Andi
