does it make sense to build a kernel for MPC8360e without FSL_LBC?

[Robert P. J. Day]

(hope this question is on topic for this list.)

  long story short: was handed a fairly old box based on MPC8360e on
which to install linux based on yocto project (well, technically, wind
river linux 7 but ... same difference).

  was handed an initial, first pass at a BSP, included a perfectly
adequate u-boot, kernel and root filesystem, and sure enough, it
boots. however, here's the issue.

  i can see from the architecture overview that there are a number of
things hanging off the processor's local bus, including boot flash, an
FPGA, some embedded DSPs, and more. but absolutely none of that shows
up in the boot messages, under /sys and so on.

  looked more carefully and the kernel configuration doesn't select
the config option FSL_LBC. i'm not a powerpc expert -- doesn't one
*need* to select that option to have access to anything on the local
bus?

  and if local bus support *is* configured into the kernel, where
would i see evidence of that? thanks muchly.
