[U-Boot] [PATCH 0/3] Fix for rare beaglebone ethernet failures

[Sekhar Nori <nsekhar@ti.com>]

There have been reports of ethernet network failures on beagle
bone black. These have been root caused to ethernet PHY latching
to a different address on boot than what is programmed in DT.

See: https://groups.google.com/d/msg/beagleboard/9mctrG26Mc8/1FuI_i5KW10J

This patch series tries to workaround this suitaiton by patching
device-tree passed to kernel with the correct address. As well as
updating the PHY address U-Boot drivers themselves use.

Tested on beaglebone black rev A4 by simulating the error condition
I was also able to hit the actual hardware error once in a while.

  drivers: net: cpsw: add support to update phy address
  board: ti: am335x: add support to fixup phy address
  configs: am335x_evm: enable OF_BOARD_SETUP
