Thank you for your prompt reply.

You are welcome.

Could you please tell me where I can get or how to build a PPC cross version
of GDB.

You can download the latest  version  of  our  ELDK  (Embedded  Linux
Development  Kit)  from ftp://ftp.leo.org/pub/eldk/2.1.0/, please see
ftp://ftp.leo.org/pub/eldk/2.1.0/eldk-ppc-linux-x86/README.html    or
http:www.denx.de/re/ELDK.html for detailed instructions.

Also, I have following questions I can't find the answer:
Is it enough just to include kgdb support when configuring kernel to build
linux kernel with kgdb support?
Has DENX's linux-2.4.4 kernel been patched with kgdb already or not?

Actually, we don't use kgdb. We  use  the  Abatron  BDI2000  for  all
kernel and device driver debugging (on PPC, ARM, and MIPS).

Are the ? marks shown on serial console when kernel built with kgdb support
starts run supposed to see or some else?

kgdb  will  stop  at  a  built-in  breakpoint  pretty  early  in  the
initialization  sequence  to  allow  you  to set more breakpoints for
example to debug drivers etc. It expects  that  you  connect  with  a
debugger on the serial line.

Best regards,

Wolfgang Denk
