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

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

68 default MPC8xx_SECOND_ETH_FEC2
70 config MPC8xx_SECOND_ETH_FEC2
74 Enable FEC2 to serve as 2-nd Ethernet channel. Note that SMC2
75 (often 2-nd UART) will not work if this is enabled.
77 config MPC8xx_SECOND_ETH_SCC3
81 Enable SCC3 to serve as 2-nd Ethernet channel. Note that SMC1
82 (often 1-nd UART) will not work if this is enabled.

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