initrd problem

[Ed Martini <martini@c2micro.com>]

Background:

I'm trying to get 2.6.11 to run on a MIPS Malta board with Yamon.  The 
kernel that comes with the board is 2.4.18 with an embedded ramdisk that 
runs some scripts to install RPMS via NFS or CD-ROM.  The kernel is 
converted to s-records via objcopy(1), and loaded into memory via tftp.  
I want to do something similar with 2.6.latest.

Problem:

On or about Nov 21 of last year, the CONFIG_EMBEDDED_RAMDISK disappeared.

In it's place it is suggested to use the tools in arch/mips/boot, so I 
tried it.  I can cross-compile the kernel, and I get an ELF vmlinux.  I 
can convert it to ecoff with elf2ecoff, and attach an initrd image with 
addinitrd.  The problem begins here.  I end up with an ecoff format 
kernel which is not recognized by objcopy(1), and therefore no s-records.

It seems there is a program called gensrec that would do the job, but 
google doesn't want to tell me where to get it.  Some IRIX binary perhaps?

Solution?

Should I put CONFIG_EMBEDDED_RAMDISK and its ilk back into my kernel, or 
write an ELF version of addinitrd?  Other ideas?

Thanks in advance.
