	* console/console.c, include/commproc.h, startup/start.S:
	The printk/printf did not work when loaded by EPPCBUG. They did
	work when loaded with the BDM debugger.  I suspected EPPBUG
	made some nasty things like patching Communication processor
	microcode...  Anyway, the attached patch:
          1) Enables to have printk nearly immediately after boot,
          2) Make printf work automagically (I do not know why except I make a
	different initialization for printk that should be overwritten by
	console init later ?)

	I let the default to be using EPPCBUG embedded firmware to boot and
	using this printk early enabler code (LOADED_BY_EPPCBUG and
	EARLY_CONSOLE) are on.
