From 60b74bde9280e85f4423c05a50ecc41de56ad980 Mon Sep 17 00:00:00 2001 From: Daniel Schwierzeck Date: Wed, 27 Jul 2011 13:22:36 +0200 Subject: MIPS: INCA-IP: rename inca-swap-bytes host tool The INCA-IP SoC belongs to the Lantiq XWAY SoC product portfolio. For the upcoming support of other Lantiq SoC devices this tool should not solely depend on the INCA-IP board. Rename the tool to xway-swap-bytes and add an config option to enable compilation optionally.
