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.

32 Freescale Semiconductor MPC885 Application Development System (ADS).
34 The MPC885ADS is meant to serve as a platform for s/w and h/w

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.

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

69 Enable FEC2 to serve as 2-nd Ethernet channel. Note that SMC2
70 (often 2-nd UART) will not work if this is enabled.
72 config MPC8xx_SECOND_ETH_SCC3
76 Enable SCC3 to serve as 2-nd Ethernet channel. Note that SMC1
77 (often 1-nd UART) will not work if this is enabled.

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