31 Freescale Semiconductor MPC885 Application Development System (ADS).
33 The MPC885ADS is meant to serve as a platform for s/w and h/w
34 development around the MPC885 processor family.
37 bool "Embedded Planet EP88xC (a.k.a. CWH-PPC-885XN-VE)"
39 select PPC_CPM_NEW_BINDING
41 This enables support for the Embedded Planet EP88xC board.
43 This board is also resold by Freescale as the QUICCStart
44 MPC885 Evaluation System and/or the CWH-PPC-885XN-VE.

52 bool "Second Ethernet channel"
56 This enables support for second Ethernet on MPC885ADS and MPC86xADS boards.
57 The latter will use SCC1, for 885ADS you can select it below.

62 default MPC8xx_SECOND_ETH_FEC2
64 config MPC8xx_SECOND_ETH_FEC2
68 Enable FEC2 to serve as 2-nd Ethernet channel. Note that SMC2
69 (often 2-nd UART) will not work if this is enabled.
71 config MPC8xx_SECOND_ETH_SCC3
75 Enable SCC3 to serve as 2-nd Ethernet channel. Note that SMC1
76 (often 1-nd UART) will not work if this is enabled.

94 bool "Copy-Back Data Cache (else Writethrough)"
96 Saying Y here will cause the cache on an MPC8xx processor to be used
97 in Copy-Back mode. If you say N here, it is used in Writethrough
100 If in doubt, say Y here.
103 bool "CPU6 Silicon Errata (860 Pre Rev. C)"
105 MPC860 CPUs, prior to Rev C have some bugs in the silicon, which
106 require workarounds for Linux (and most other OSes to work). If you
107 get a BUG() very early in boot, this might fix the problem. For
108 more details read the document entitled "MPC860 Family Device Errata
109 Reference" on Freescale's website. This option also incurs a
112 If in doubt, say N here.
115 bool "CPU15 Silicon Errata"
118 This enables a workaround for erratum CPU15 on MPC8xx chips.
119 This bug can cause incorrect code execution under certain
120 circumstances. This workaround adds some overhead (a TLB miss
121 every time execution crosses a page boundary), and you may wish
122 to disable it if you have worked around the bug in the compiler
123 (by not placing conditional branches or branches to LR or CTR
124 in the last word of a page, with a target of the last cache
125 line in the next page), or if you have used some other
128 If in doubt, say Y here.
