            Bug ID: 1002061
           Summary: Freescale eDMA library macro
                    FREESCALE_EDMA_NBYTES_MLOFFYES_MLOFF() fails with
                    negative offset.
           Product: eCos
           Version: CVS
            Target: freescale_twr_k70f120m (Freescale Kinetis TWR-K70F120M
                    board)

Patch for freescale_edma.h - mask-off unwanted birs.

Freescale eDMA library macro FREESCALE_EDMA_NBYTES_MLOFFYES_MLOFF()fails when
offset is negative.
The reason: The ofset field is 20 bit long, so signe extended negative number
has extra leading 1s that polute register bits out of offset boundaries.

The attached patch masks off bits out of offset field boundaries.
