wic: allow creation of partitions not in table

2015-02-14T08:40:34+00:00

For some architectures it is necessary to reserve space on disk without
it being present in the partition table.

For example, u-boot on i.mx is placed at an offset of 1kB on the sdcard.
While it would be possible to create a partition at that offset and
place u-boot there, it would then be necessary to update the default
u-boot environment to use partition 2 on the mmc instead of partition 1.

wic: use kB for the partitions size

2015-02-07T18:52:45+00:00

Use kB instead of MB for the partition size to get a better granularity.

This is needed on some SoC (i.mx, omap) where it is necessary to create
partitions as small as 64kB.

Keep the backward compatibility by assuming MB when no unit is provided.

wic: fix extended/logical partition layout

2015-02-07T13:30:56+00:00

The patch fixes an issue in laying out extended and logical partitions
by wic. The original code produced disk images in which the size 3rd
partition as described in MBR was incorrect. Depending on the type of
file system used for that partition and size of the partition, it would
be impossible to mount the partition correctly. For instance, kickstart
file in which the 3rd partition had size of 1GB and used ext4 fs, would
result in an image with an umountable partition. The root cause is
reservation of sectors for EBR through stealing of last sector from the
last primary partition.

scripts: use '/usr/bin/env' in shebangs with python

2014-11-12T15:35:42+00:00

To support yocto on systems with python3 as default version, scripts
should use /usr/bin/env python in the shebang, as this allows the use of
a fake env to mimic python2 as default version.

This patch simply replaces occurrences of #!/usr/bin/python with
 #!/usr/bin/env python and was done with this oneliner:

     git grep -lE '^#!/usr/bin/python' | xargs \
         sed -i 's|/usr/bin/python|/usr/bin/env python|'

wic: do not realign aligned partitions

2014-08-23T08:25:04+00:00

The change prevents additional realignment of already aligned
partition. Previously, even already aligned partitions would be pushed
forward by the amount of --align.

wic: do not steal sectors from the first partition

2014-08-23T08:25:04+00:00

In order to make up for space loss due to overhead located before the
first partition, same amount of bytes was extracted from the first
partition's size. This leads to unexpected change of first partition's
size, and is not matched by similar adjustment at the time the partition
image is generated. Thus it is possible that the first partition may
partially overwrite contents of the following partition, as the
partition image is larger than the allocated space.

This is also problematic on certain platforms such as OMAP, where the
first partition is required for have an even number of
sectors (typically already expressed by --size in kickstart
file). Subtracting an odd number of sectors lost for overhead, leads to
an odd number of sectors assigned for partition, preventing the board,
such as beaglebone, from booting correctly.

wic: Rename /mic to /wic

2014-08-11T09:52:19+00:00

As well as any other stray instances of mic in the codebase that can
be removed.

We don't really need to carry around legacy naming, and the history is
in git.
