Subject: Convert MPC8641HPCN to use libfdt.
X-Git-Tag: v2008.10-rc1~808^2~33^2~47
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ea9f7395ec362584e5e4f266bd0b0c4422cf6a4c;p=platform%2Fkernel%2Fu-boot.git

Convert MPC8641HPCN to use libfdt.

Assumes the presence of the aliases node in the DTS to
locate the ethernet, pci and serial nodes for fixups.

Use consistent fdtaddr and fdtfile in environment variables.
