Re: Floating point in 8260

[Jim Lewis <jlewis@mvista.com>]

If you are dead-set against upgrading the CPU, you can run a root filesystem
that is COMPLETELY without FP instructions (built to use soft-float). The
MontaVista 8xx CDK should work fine.  Just make sure you don't mix it (the 8xx
CDK) with other binaries.
