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
56 This enables support for the Keymile MGSUVD board.
62 support for the mpc8xx based boards from TQM.

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

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