uartlite with 2.6.17 kernel and kernel early text messages

[Robert Corley <rcorley@aegis-inc.net>]

I am still trying to get the UARTLITE to work with 2.6 and a plb_temac desi=
gn.  I am using EDK 7.1.  I have generated the edk files and copied xparame=
ters_ml300.h to arch/ppc/platforms/4xx/xparameters.xparameters_ml403.h=0A=
=0AIn an effort to get past the "Rebooting to System ACE Configuration Addr=
ess 6..." message, I have selected "support for early boot texts over seria=
l port" in kernel debugging.=0A=0AFYI, I'm using Peter's patches to create =
the uartlite.c and associated files and have selected the uartlite using ma=
ke menuconfig.=0A=0AThe first error is as follows:=0Aathena startup_network=
