Don't hard code the location of m5AlphaAccess. Instead, move the
code into a function that can be called by the AlphaConsole class. AlphaConsole will pass in its address. arch/alpha/ev5.hh: Move Phys2K0Seg to ev5.hh and fixup the TSUNAMI uncacheable bits so that they will be converted correctly. dev/alpha_access.h: Do not hard code the location of the AlphaConsole dev/alpha_console.cc: fixup #includes tell the system where the alpha console is sim/system.hh: Provide a function that will tell the system where the AlphaAccess structure (device) lives --HG-- extra : convert_revision : 92d70ca926151a32eebe9925de597459ac58013e
