[U-Boot] [PATCH 0/3] Update MAC address in "ethernet" node of Linux device tree

[Prabhakar Kushwaha]

Current implementation of MAC address fix-up of device tree uses
tailing number behind "ethernet" found in "/aliases".  It is not
necessary for trailing number of “ethernet” to be sequential. There
can be hole in between or any node disabled.

hole can be created based on SerDes protocol supported by SoCs.
Usually Linux device tree contains "ethernet" node for all possible
interface supported by SoC i.e. LS1046A. Where based on SerDes
protocol some "ethernet" interface are unavailable. 

This patch-set provide way to fetch MAC addr sequentially from env
variables and also create hole in "ethernet" node (disable) based
on SerDes protocol for LS1046ARDB.

Other platforms can also follow same approach. 

Prabhakar Kushwaha (3):
  common: Fix-up MAC addr in dts by fetching env variable serially
  arm: Add support of updating dts before fix-up
  boards: ls1046ardb: disable unavailable "ethernet" node in dts
