config SCC_ENET
	bool "CPM SCC Ethernet"

	help
	  Enable Ethernet support via the Motorola MPC8xx serial
	  communications controller.

config SCC1_ENET
	bool "SCC1"
	help
	  Use MPC8xx serial communications controller 1 to drive Ethernet
	  (default).

config SCC2_ENET
	bool "SCC2"
	help
	  Use MPC8xx serial communications controller 2 to drive Ethernet.

	help
	  Use MPC8xx serial communications controller 3 to drive Ethernet.

config FEC_ENET
	bool "860T FEC Ethernet"
	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.

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.

	default NO_UCODE_PATCH
	help
	  Help not implemented yet, coming soon.
