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)
Architecture/Host All
OS:
Status: NEW
Severity: enhancement
Priority: low
Component: HAL
Assignee: unassigned@bugs.ecos.sourceware.org
Reporter: ilijak@siva.com.mk
CC: ecos-bugs@ecos.sourceware.org

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.
