2007-08-07sh: panic on machvec section misalignment.Paul Mundt
Now that __initmv references the machvec section unconditionally there have been cases where folks have been mistakenly flagging non-machvec structures with the machvec section attribute (presumably to shut up modpost). This leads to obscure breakage in earlyprintk amongst other places and is rather non-obvious. Add a simple sanity check to try and catch __initmv misuse and panic early.

2007-06-08sh: Rip out special unknown machvec.Paul Mundt
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. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Kill off machvec aliases.Paul Mundt
We now throw all of the machvecs in to .machvec.init and either select one on the command line, or copy out the first (and usually only) one to sh_mv. The rest are freed as usual. This gets rid of all of the silly sh_mv aliasing and makes the selection explicit rather than link-order dependent. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Fixup machvec support.Paul Mundt
This fixes up much of the machvec handling, allowing for it to be overloaded on boot. Making practical use of this still requires some Kconfig munging, however. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
