* 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.
