23 MPC86x Application Development System by Freescale Semiconductor.
24 The MPC86xADS is meant to serve as a platform for s/w and h/w
25 development around the MPC86X processor families.
30 select PPC_CPM_NEW_BINDING
32 Freescale Semiconductor MPC885 Application Development System (ADS).
34 The MPC885ADS is meant to serve as a platform for s/w and h/w
35 development around the MPC885 processor family.
38 bool "Embedded Planet EP88xC (a.k.a. CWH-PPC-885XN-VE)"
40 select PPC_CPM_NEW_BINDING
42 This enables support for the Embedded Planet EP88xC board.
44 This board is also resold by Freescale as the QUICCStart
45 MPC885 Evaluation System and/or the CWH-PPC-885XN-VE.
48 bool "Analogue & Micro Adder 875"

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

74 config MPC8xx_SECOND_ETH_FEC2
78 Enable FEC2 to serve as 2-nd Ethernet channel. Note that SMC2
79 (often 2-nd UART) will not work if this is enabled.
81 config MPC8xx_SECOND_ETH_SCC3
85 Enable SCC3 to serve as 2-nd Ethernet channel. Note that SMC1
86 (often 1-nd UART) will not work if this is enabled.

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