	* Makefile.am: Added custom memcpy().  Update for network sources.
	* configure.ac: Enable interrupt driven Termios for all BSPs.
	* ide/pcmcia_ide.c: Disable broken DMA support.
	* include/bsp.h: Fixed NEED_LOW_LEVEL_INIT define.  Set default
	console baud to 115200.
	* include/irq.h, irq/irq.c: Fixed interrupt handling to avoid the
	following problems: 1. multiple invokation of peripheral interrupt
	handlers, 2. missing synchronization after mask write and enabling of
	external exceptions, and 3. logic overhead.
	* network_5200/network.c: Added MII interface.  Fixed controller
	restart after FIFO errors.  Performance improvements.
	* start/start.S: Fixed ROM startup.  Initialize XLB arbiter for all
	BSPs.
	* startup/bspstart.c: Special intialization for MPC5200B (B variant).
	Install standard alignment handler.
	* startup/cpuinit.c, startup/linkcmds.brs5l, startup/linkcmds.dp2,
	startup/linkcmds.icecube, startup/linkcmds.pm520_cr825,
	startup/linkcmds.pm520_ze30: Avoid accesses outside the RAM area.
