Subject: [PATCH] core-image-sato-sdk-ptest: reduce size
Precedence: list

This image is very large and is skirting the maximum size of hddimg images (4GB,
as they're embedded inside FAT partitions).  Making the image 10MB bigger can be
enough to cause the build to fail.  This image is also used by QA so currently
we need to keep it working.

The default values for expanding an image to give it usable space are quite
generous, (3GB rootfs * 1.3 gives 1GB of empty space), so change the overhead
multiplier to 1.0x and explicitly request just 0.5GB of empty space in the
images.

This should give us a bit more breathing room until we can either remove hddimg
from the default build, or make this image dramatically smaller.
