The MPC86xADS is meant to serve as a platform for s/w and h/w development around the MPC86X processor families. config MPC885ADS bool "MPC885ADS" select CPM1 select OF_DYNAMIC help Freescale Semiconductor MPC885 Application Development System (ADS). Also known as DUET. The MPC885ADS is meant to serve as a platform for s/w and h/w development around the MPC885 processor family. config PPC_EP88XC bool "Embedded Planet EP88xC (a.k.a. CWH-PPC-885XN-VE)" select CPM1 help This enables support for the Embedded Planet EP88xC board. This board is also resold by Freescale as the QUICCStart MPC885 Evaluation System and/or the CWH-PPC-885XN-VE. config PPC_ADDER875 bool "Analogue & Micro Adder 875" select CPM1 help This enables support for the Analogue & Micro Adder 875 board. config TQM8XX bool "TQM8XX" select CPM1 help support for the mpc8xx based boards from TQM. endchoice menu "Freescale Ethernet driver platform-specific options" depends on (FS_ENET && MPC885ADS) config MPC8xx_SECOND_ETH bool "Second Ethernet channel" depends on MPC885ADS default y help This enables support for second Ethernet on MPC885ADS and MPC86xADS boards.

Note that SMC2 (often 2-nd UART) will not work if this is enabled. config MPC8xx_SECOND_ETH_SCC3 bool "SCC3" depends on MPC885ADS help Enable SCC3 to serve as 2-nd Ethernet channel. Note that SMC1 (often 1-nd UART) will not work if this is enabled. endchoice endmenu # # MPC8xx Communication options # menu "MPC8xx CPM Options" depends on PPC_8xx # This doesn't really belong here, but it is convenient to ask # 8xx specific questions. comment "Generic MPC8xx Options" config 8xx_COPYBACK bool "Copy-Back Data Cache (else Writethrough)" help Saying Y here will cause the cache on an MPC8xx processor to be used in Copy-Back mode. If you say N here, it is used in Writethrough mode. If in doubt, say Y here. config 8xx_GPIO bool "GPIO API Support" select GPIOLIB help Saying Y here will cause the ports on an MPC8xx processor to be used with the GPIO API. If you say N here, the kernel needs less memory. If in doubt, say Y here. config 8xx_CPU15 bool "CPU15 Silicon Errata" depends on !HUGETLB_PAGE default y help This enables a workaround for erratum CPU15 on MPC8xx chips. This bug can cause incorrect code execution under certain circumstances. This workaround adds some overhead (a TLB miss every time execution crosses a page boundary), and you may wish to disable it if you have worked around the bug in the compiler (by not placing conditional branches or branches to LR or CTR in the last word of a page, with a target of the last cache line in the next page), or if you have used some other workaround.
