wic: allow to configure extra space per partition

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

Introduce a new option --extra-space instead of using IMAGE_EXTRA_SPACE.
This is useful for boot partitions where the extra space is often
useless or for huge partition where 10MiB may not be enough.

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: Remove special-case bootimg_dir

2014-10-30T13:03:30+00:00

The first iterations of wic very shortsightedly catered to two
specific use-cases and added special-purpose params for those cases so
that they could be directly given their corresponding boot artifacts.
(hdddir and staging_data_dir).

As more use-cases are added, it becomes rather obvious that such a
scheme doens't scale, and additionally causes confusion for plugin
writers.

This removes those special cases and states explicitly in the help
text that plugins are responsible for locating their own boot
artifacts.

wic: Update the help text to include -D (--debug)

2014-10-30T13:03:30+00:00

The --debug option is missing from the wic help text; this adds it and
at the same time rearranges the usage into a more logical arrangement.

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.

wic: Update 'Background and Motivation' help section

2014-08-11T09:52:17+00:00

Remove help text regarding the source and future intentions of the wic
codebase, since the code prompting those comments has now been mostly
removed.

transcribing wic help for the dev manual.
