Hi David,
This patch should remove the last of the prom_printf/prom_halt code from
the driver directories with two exceptions.
If you do not have any issues with the changes, please can you apply
them.
I looked at the remaining two files containing prom_printf
(drivers/serial/dz.c - only used for debugging, and
drivers/video/console/promcon.c - used to display info) and can see no
inapropriate uses of prom_printf.
Is I understant it, prom_printf/prom_halt should only be used for
debugging code and only where printk/panic does not have the desired
effect when used on a kernel booted with -p.

[SPARC32] Remove prom_printf and prom_halt
prom_printf and prom_halt should only be used as a last resort. If a system is
failing very early on in boot, the -p parameter can (and should) be used so
that generic driver code does not get plouted with architecture specific code.

I only have a CG3 and have been using a similar patch for some time. I made
the changes back in 2.6.8.1 when trying to find out why the CG3 console was
broaken. Black on Black is very dificult to read :).
