[Buildroot] RTAI Working

[Ravi Chemudugunta]

Hello,

RTAI, working with some workarounds.

RTAI requires that the kernel be patched, and that the sources for the
kernel are available.
This creates a circular dependency (unless it is possible for RTAI to
depend on the extract
stage of the kernel).

I have gotten around the requirement to patch, by using kernel patch
feature in build root and pointing
it to a pre-extracted patch.

I am also doing the same to address the requirement that the kernel
sources be made known to
RTAI. Is it possible to use some kind of an auto-global $KERNEL_SOURCE_DIR?
I am thinking of using the set k-options function (as used in busybox
- RTAI uses a .config file, similar
 to that of the linux kernel and busybox) to set this path?

cheers,
