From da2014a2b080e7f3024a4eb6917d47069ad9620b Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Tue, 29 Jul 2008 21:01:19 +0900 Subject: sh: Shuffle the board directories in to mach groups. This flattens out the board directories in to individual mach groups, we will use this for getting rid of unneeded directories, simplifying the build system, and becoming more coherent with the refactored arch/sh/include topology.
