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"
49 This enables support for the Analogue & Micro Adder 875
56 support for the mpc8xx based boards from TQM.

63 config MPC8xx_SECOND_ETH
64 bool "Second Ethernet channel"
68 This enables support for second Ethernet on MPC885ADS and MPC86xADS boards.
69 The latter will use SCC1, for 885ADS you can select it below.

73 depends on MPC8xx_SECOND_ETH
74 default MPC8xx_SECOND_ETH_FEC2
76 config MPC8xx_SECOND_ETH_FEC2
80 Enable FEC2 to serve as 2-nd Ethernet channel. Note that SMC2
81 (often 2-nd UART) will not work if this is enabled.
83 config MPC8xx_SECOND_ETH_SCC3
87 Enable SCC3 to serve as 2-nd Ethernet channel. Note that SMC1
88 (often 1-nd UART) will not work if this is enabled.

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