18 MPC86x Application Development System by Freescale Semiconductor.
19 The MPC86xADS is meant to serve as a platform for s/w and h/w
20 development around the MPC86X processor families.
27 Freescale Semiconductor MPC885 Application Development System (ADS).
29 The MPC885ADS is meant to serve as a platform for s/w and h/w
30 development around the MPC885 processor family.
33 bool "Embedded Planet EP88xC (a.k.a. CWH-PPC-885XN-VE)"
36 This enables support for the Embedded Planet EP88xC board.
38 This board is also resold by Freescale as the QUICCStart
39 MPC885 Evaluation System and/or the CWH-PPC-885XN-VE.
42 bool "Analogue & Micro Adder 875"
45 This enables support for the Analogue & Micro Adder 875
52 support for the mpc8xx based boards from TQM.

59 config MPC8xx_SECOND_ETH
60 bool "Second Ethernet channel"
64 This enables support for second Ethernet on MPC885ADS and MPC86xADS boards.
65 The latter will use SCC1, for 885ADS you can select it below.
68 prompt "Second Ethernet channel"
69 depends on MPC8xx_SECOND_ETH
70 default MPC8xx_SECOND_ETH_FEC2
72 config MPC8xx_SECOND_ETH_FEC2
76 Enable FEC2 to serve as 2-nd Ethernet channel. Note that SMC2
77 (often 2-nd UART) will not work if this is enabled.
79 config MPC8xx_SECOND_ETH_SCC3
83 Enable SCC3 to serve as 2-nd Ethernet channel. Note that SMC1
84 (often 1-nd UART) will not work if this is enabled.

102 bool "Copy-Back Data Cache (else Writethrough)"
104 Saying Y here will cause the cache on an MPC8xx processor to be used
105 in Copy-Back mode. If you say N here, it is used in Writethrough
108 If in doubt, say Y here.
111 bool "GPIO API Support"
114 Saying Y here will cause the ports on an MPC8xx processor to be used
115 with the GPIO API. If you say N here, the kernel needs less memory.
117 If in doubt, say Y here.
120 bool "CPU6 Silicon Errata (860 Pre Rev. C)"
122 MPC860 CPUs, prior to Rev C have some bugs in the silicon, which
123 require workarounds for Linux (and most other OSes to work). If you
124 get a BUG() very early in boot, this might fix the problem. For
125 more details read the document entitled "MPC860 Family Device Errata
126 Reference" on Freescale's website. This option also incurs a
129 If in doubt, say N here.
132 bool "CPU15 Silicon Errata"
133 depends on !HUGETLB_PAGE
136 This enables a workaround for erratum CPU15 on MPC8xx chips.
137 This bug can cause incorrect code execution under certain
138 circumstances. This workaround adds some overhead (a TLB miss
139 every time execution crosses a page boundary), and you may wish
140 to disable it if you have worked around the bug in the compiler
141 (by not placing conditional branches or branches to LR or CTR
142 in the last word of a page, with a target of the last cache
143 line in the next page), or if you have used some other
146 If in doubt, say Y here.
