Static layout: Generate tar.gz for static layout pnor

2019-03-13T03:01:49+00:00

Add --image_type option to specify the image type of generated PNOR in tarball. Support "squashfs" and "static" image types. Rename `generate-squashfs` to `generate-tar` to reflect that this util is to generate a tarball instead of squashfs. Example of usage: # Generate unsigned tarball for Witherspoon ./generate-tar -i squashfs witherspoon.pnor # Generate signed tarball with default key for Witherspoon ./generate-tar -i squashfs -s -- witherspoon.pnor # Generate unsigned tarball for Romulus ./generate-tar -i static romulus.pnor # Generate signed tarball with default key for Romulus ./generate-tar -i static -s -- romulus.pnor Tested: Verify the generated tarball contains correct files.

Always clean up the scratch dir

2017-11-06T18:20:43+00:00

The scratch directory, holding the extracted squashfs image and the temporary UBI image, can be quite large, >40MB. Use trap to make sure it always gets cleaned up. Signed-off-by: Gunnar Mills Change-Id: I0289036dcf2bbf40fc76cf5ebf9dde1d47379435

Create UBI image

2017-11-06T18:08:20+00:00

Create a 128MiB UBI image with 3 volumes: a static pnor-ro-, a dynamic pnor-rw-, and a dynamic pnor-prsv. The pnor-ro- is created from the squashfs file. pnor-rw- and pnor-prsv are both empty and size 16MiB and 2MiB respectively. A future enhancement would be to pass in the size of the image.

Untar tarball and check for squashfs file

2017-11-06T18:08:10+00:00

Untar the tarball and then check for existence of pnor.xz.squashfs file. A PNOR SquashFS Tarball must have a pnor.xz.squashfs file. A similar check is done is in the openpower item updater. Change-Id: Id6e63ee088941044ecc22282bd5abd6358d17d87 Signed-off-by: Gunnar Mills
