• mpc8xx/console-generic/console-generic.c: 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.
