Even though support for the p5020's on-chip ethernet is not yet upstream,
it is not appropriate to disable all networking support (including
loopback, unix domain sockets, external ethernet devices, etc) in the
defconfig.  The networking settings are taken from mpc85xx_smp_defconfig,
minus the drivers for ethernet devices not found on any current e5500
chip.

The other changes are the result of running "make savedefconfig".

Hi Scott,

I remember in previous testing that this option has a negative effect on pe=
rformance.  Do we really need it to be enabled?

I didn't change this setting, it just moved due to running it through
savedefconfig.

What was the performance impact?

It adds CPU cycles to the interrupt handling path.  Will cause performance =
drop for benchmarks with large amount of interrupts such as IP forwarding.
