            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

Created attachment 2589
  --> http://bugs.ecos.sourceware.org/attachment.cgi?id=2589&action=edit
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.

[This e-mail has been automatically generated.]

You have one or more bugs assigned to you in the Bugzilla bug tracking system (http://bugs.ecos.sourceware.org/) that require
attention.

All of these bugs are in the CONFIRMED
state, and have not been touched in 7 days or more.
You need to take a look at them, and decide on an initial action.

Generally, this means one of three things:

(1) You decide this bug is really quick to deal with (like, it's INVALID),
    and so you get rid of it immediately.
(2) You decide the bug doesn't belong to you, and you reassign it to
    someone else. (Hint: if you don't know who to reassign it to, make
    sure that the Component field seems reasonable, and then use the
    "Reset Assignee to default" option.)
(3) You decide the bug belongs to you, but you can't solve it this moment.
    Accept the bug by setting the status to IN_PROGRESS.

To get a list of all CONFIRMED bugs, you can use this URL (bookmark
it if you like!):
http://bugs.ecos.sourceware.org/buglist.cgi?bug_status=CONFIRMED&assigned_to=unassigned@bugs.ecos.sourceware.org

Or, you can use the general query page, at
http://bugs.ecos.sourceware.org/query.cgi

Appended below are the individual URLs to get to all of your CONFIRMED bugs
that haven't been touched for 7 days or more.

You will get this message once a day until you've dealt with these bugs!
