From efa35cf12d914d4caba942acd5a6c45f217de302 Mon Sep 17 00:00:00 2001 From: Grzegorz Bernacki Date: Fri, 15 Jun 2007 11:19:28 +0200 Subject: ppc4xx: Clean up 440 exceptions handling - Introduced dedicated switches for building 440 and 405 images required for 440-specific machine instructions like 'rfmci' etc. - Exception vectors moved to the proper location (_start moved away from the critical exception handler space, which it occupied) - CriticalInput now serviced (with default handler) - MachineCheck properly serviced (added a dedicated handler and return subroutine) - Overall cleanup of exceptions declared with STD_EXCEPTION macro (unused, unhandled and those not relevant for 4xx were eliminated) - Eliminated Linux leftovers, removed dead code Signed-off-by: Grzegorz
