This and the following patches are pretty complicated. Given that interest in
MIPS in general seems to be declining, and given that Vicente is no longer
contributing to Buildroot, we feel that there is a big risk that this stuff is
just going to bitrot and little chance that anybody will actually ever use this.
Therefore, I've marked these patches as Rejected in patchwork.
If anybody feels they need this, feel free to resend. For your convenience,
here are the patchwork URLs:
