5 menu "MPC8xx CPM Options"
9 bool "CPM SCC Ethernet"
10 depends on NET_ETHERNET
12 Enable Ethernet support via the Motorola MPC8xx serial
13 communications controller.
16 prompt "SCC used for Ethernet"
23 Use MPC8xx serial communications controller 1 to drive Ethernet
29 Use MPC8xx serial communications controller 2 to drive Ethernet.
34 Use MPC8xx serial communications controller 3 to drive Ethernet.
39 bool "860T FEC Ethernet"
40 depends on NET_ETHERNET
42 Enable Ethernet support via the Fast Ethernet Controller (FCC) on
46 bool "Use MDIO for PHY configuration"
49 On some boards the hardware configuration of the ethernet PHY can be
50 used without any software interaction over the MDIO interface, so
51 all MII code can be omitted. Say N here if unsure or if you don't
52 need link status reports.
55 bool "Support AMD79C874 PHY"
59 bool "Support LXT970 PHY"
63 bool "Support LXT971 PHY"
67 bool "Support QS6612 PHY"
70 config ENET_BIG_BUFFERS
71 bool "Use Big CPM Ethernet Buffers"
72 depends on SCC_ENET || FEC_ENET
74 Allocate large buffers for MPC8xx Ethernet. Increases throughput
75 and decreases the likelihood of dropped packets, but costs memory.
78 bool "Embedded Planet HIOX Audio"
81 # This doesn't really belong here, but it is convenient to ask
82 # 8xx specific questions.

86 bool "Copy-Back Data Cache (else Writethrough)"
88 Saying Y here will cause the cache on an MPC8xx processor to be used
89 in Copy-Back mode. If you say N here, it is used in Writethrough
92 If in doubt, say Y here.
95 bool "CPU6 Silicon Errata (860 Pre Rev. C)"
97 MPC860 CPUs, prior to Rev C have some bugs in the silicon, which
98 require workarounds for Linux (and most other OSes to work). If you
99 get a BUG() very early in boot, this might fix the problem. For
100 more details read the document entitled "MPC860 Family Device Errata
101 Reference" on Motorola's website. This option also incurs a
104 If in doubt, say N here.
