MPC86x Application Development System by Freescale Semiconductor.
The MPC86xADS is meant to serve as a platform for s/w and h/w
development around the MPC86X processor families.

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.

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.

Enable FEC2 to serve as 2-nd Ethernet channel. Note that SMC2
(often 2-nd UART) will not work if this is enabled.

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

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.
If in doubt, say Y here.
