The CPU support is really separate from the platform, and
ARM9TDMI/ARM940T is supported by the platform-independent code.

In the s3c2510-specific portion, you should need very little
code that has dependencies on the specific ARM code besides
for the Kconfig 'select CPU_ARM940T' statement.

No problem at all, these things are not well documented, so it's
good if at least people can refer to this conversation in the
email archives.
