qnxbasedma.build

Here's the buildfile for .boot on an x86 platform, qnxbasedma.build.

Note: In a real buildfile, you can't use a backslash (\) to break a long line into shorter pieces, but we've done that here, just to make the buildfile easier to read.

# image will be used directly without making a copy of the data
# (i.e., as the default "data=cpy" does). When they have been
# run once, they will be unlinked from /proc/boot.
