Using Ralf's pre-packaged mips64 gcc 2.95.4 / binutils 2.13.2.1 .rpm, I
wasn't able to get this to build without having CPU-specific gcc opts

Arggh.. my (different) build environment meant messing with options in my
arch/mips64/Makefile (like using "-march=rm9000" instead of
"-mcpu=r8000 -mips4").
The CFLAGS change below looks fine.
Btw, an ifdef for CONFIG_CPU_RM7000 will be required too, using the
same CFLAGS options as the rm9000.

yes
At this point (with latest linux_2_4 tree), I can boot the kernel but get
a hang after mounting NFS root via the gt64340 eth0. If I can find a
serial cable for the second port, I might try to step with kgdb...
Thanks,
Will

Ralf,
Here is 64-bit support for both the RM7000-based Ocelot-C and
RM9000-based Jaguar ATX platforms.
Since the port was 2.4.21 based, this patch submission is for the 2.4 tree.
This patch supersedes the Ocelot-C patch I sent earlier, since it
encompasses both platforms.
Notes the board support lives under arch/mips/momentum.
Also, CONFIG_BOARD_SCACHE and CONFIG_RM7000_CPU_SCACHE are utilized and
integrated into each platform's default configuration files.
As in the first patch, drivers/net/mv64340_eth.{c,h} is added to provide
ethernet support.
If it looks ok, please check changes into the tree.
Regards,
Louis
