Currently, in Buildroot, we havea few packages that depend on the 'mtd'
package;

  - fs/kffs2/
  - fs/ubifs/
      both want the mtd tools

  - busybox
      installs mtd applets

  - swupdate
      needs the headers

There are a few other refrences to '\<mtd\>', but none are about a build
dependency.

So, for Buildroot, only swupsdate seems to be impacted, indeed.

Still, using headers internal to another package is not nice from
swupdate...

Yann E. MORIN.
