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.
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)"
40 This enables support for the Embedded Planet EP88xC board.
42 This board is also resold by Freescale as the QUICCStart
43 MPC885 Evaluation System and/or the CWH-PPC-885XN-VE.
46 bool "Analogue & Micro Adder 875"
50 This enables support for the Analogue & Micro Adder 875
57 support for the mpc8xx based boards from TQM.

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

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