-From: Rod Whitby <rod@whitby.id.au>
-Subject: ixp4xx: Merge nslu2-power.c into nslu2-setup.c (Patch #4807)
-
-There is no reason to have power control in a separate file from the
-board setup code. Merge it back into the board setup file, removing
-superfluous header includes and removing superfluous constants from
-the machine header file.
-
-Signed-off-by: Rod Whitby <rod@whitby.id.au>
