communications controller.

(default).

config FEC_ENET

depends on NET_ETHERNET
help
Enable Ethernet support via the Fast Ethernet Controller (FCC) on
the Motorola MPC8260.
config USE_MDIO
bool "Use MDIO for PHY configuration"
depends on FEC_ENET
help
On some boards the hardware configuration of the ethernet PHY can be
used without any software interaction over the MDIO interface, so
all MII code can be omitted. Say N here if unsure or if you don't
need link status reports.

config ENET_BIG_BUFFERS
bool "Use Big CPM Ethernet Buffers"
depends on SCC_ENET || FEC_ENET
help
Allocate large buffers for MPC8xx Ethernet. Increases throughput
and decreases the likelihood of dropped packets, but costs memory.
# This doesn't really belong here, but it is convenient to ask
# 8xx specific questions.
comment "Generic MPC8xx Options"
config 8xx_COPYBACK
bool "Copy-Back Data Cache (else Writethrough)"
help
Saying Y here will cause the cache on an MPC8xx processor to be used
in Copy-Back mode. If you say N here, it is used in Writethrough
mode.
If in doubt, say Y here.
config 8xx_CPU6
bool "CPU6 Silicon Errata (860 Pre Rev. C)"
help
MPC860 CPUs, prior to Rev C have some bugs in the silicon, which
require workarounds for Linux (and most other OSes to work). If you
get a BUG() very early in boot, this might fix the problem. For
more details read the document entitled "MPC860 Family Device Errata
Reference" on Motorola's website. This option also incurs a
performance hit.
If in doubt, say N here.
