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.

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