2015-02-14wic: add GPT supportAlexandre Belloni
Add GPT partition table support. Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com> Signed-off-by: Ross Burton <ross.burton@intel.com>
2015-02-14wic: allow to configure overhead factor per partitionAlexandre Belloni
Introduce a new option --overhead-factor to replace IMAGE_OVERHEAD_FACTOR. Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com> Signed-off-by: Ross Burton <ross.burton@intel.com>
2015-02-14wic: allow to configure extra space per partitionAlexandre Belloni
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.

2015-02-14wic: allow creation of partitions not in tableAlexandre Belloni
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.

2015-02-07wic: use kB for the partitions sizeAlexandre Belloni
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.

2015-02-07wic: fix extended/logical partition layoutMaciej Borzecki
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.

2014-11-12scripts: use '/usr/bin/env' in shebangs with pythonMartin Hundebøll
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|' Signed-off-by: Martin Hundebøll <martin@hundeboll.net> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2014-10-30wic: Use overhead factor when creating partitions from rootfs directoriesTom Zanussi
When creating partitions sized to given rootfs directories, filesystem creation could fail in cases where the calculated target partition size was too small to contain the filesystem created using mkfs. This occurred in particular when creating partitions to contain very large filesystems such as those containing sdk image artifacts. This same limition is present in the oe-core image creation classes, which can be readily see by changing IMAGE_OVERHEAD_FACTOR from the default 1.3 to 1.0 and building a sato-sdk image. It should be possible to calculate required sizes exactly given the source rootfs and target filesystem types, but for now, to address the specific problem users are hitting in such situations, we'll just do exactly what oe-core does and define and use an IMAGE_OVERHEAD_FACTOR or 1.3 in those cases.

2014-08-23wic: do not realign aligned partitionsMaciej Borzecki
The change prevents additional realignment of already aligned partition. Previously, even already aligned partitions would be pushed forward by the amount of --align.

2014-08-23wic: do not steal sectors from the first partitionMaciej Borzecki
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.

2014-08-15wic: Add utility function for parsing sourceparamsTom Zanussi
Parses strings of the form key1=val1[,key2=val2,...] and returns a dict. Also accepts valueless keys i.e. without =. Signed-off-by: Tom Zanussi <tom.zanussi@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

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. Signed-off-by: Tom Zanussi <tom.zanussi@linux.intel.com>
