From fd8f20e8e2f8f1d9201086bff444c8d35f0a6a45 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Tue, 15 May 2007 15:38:30 +0900 Subject: sh: Rip out special unknown machvec. This kills off the BareCPU board as a "special" machvec, rather, we leave this as a default for when no other vector is available, or when we want to use it in combination with other vectors for testing with generic ops. As sh_mv is copied out anyways (or overloaded when an alternate vector is explicitly selected), this doesn't consume any additional memory. The generic machvec can be forcibly selected with sh_mv=generic, or by not having any other boards enabled.
