Support a selection of boot loaders in Linaro hwpacks and support multiple boards
We want to support more than one boot loader in hwpacks so that a single hwpack can offer UEFI and u-boot as well as other boot loaders. A single hwpack should also contain metadata for several boards based on the same SoC.

Whiteboard
[asac, Feb 11 2012]: acceptance could include to posting example hwpacks for all planned variations and ask concretely to validate those with lmc. In this way our PMs can better confirm that the feature was delivered and works as planned...
[dzin, Apr 7, 2012]: Assigning this a series backlog so it does not get lost
[dzin, Jun 19, 2012]: Assigning to 12.07 milestone. To be better defined.
[milo, July 9, 2012]: Created proposal hwpack config file syntax: https:/
[dooferlad, July 9, 2012]: YAML metadata with old linaro-media-create fails. Fails more nicely if you change the FORMAT file to contain "3.0"...
[milo, July 9, 2012]: Wrote wiki page explaining hwpackv3 and all its fields: https:/
[milo, July 9, 2012]: Pushed new branch with preliminary converter from INI-style syntax to YAML-syntax: lp:~milo/linaro-image-tools/multiple-boards-support/
[milo, July 10, 2012]: Discussed via email about the syntax, applied changes to the proposed one on the wiki.
[milo, July 10, 2012]: Marked workitem as postponed for now, will work on it later in the cycle.
[dzin, July 17, 2012]: At risk for delivery for July 26, but from Infra meeting on July 17, can be delivered for use by next month, close to the beginning of the cycle.
[milo, July 23, 2012]: Released Linaro Image Tools 2012.07.
[milo, July 25, 2012]: Added --read-hwpack option to linaro-
[dzin, July 27, 2012]: the following items did not make it into the 12.07 release, but were delivered shortly after:

Meta:
Headline: Support multiple boards and multiple bootloaders on a single hardware pack
Acceptance: A new hwpack format has been defined which supports multiple boot loaders and multiple boards. Linaro-hwpack create is updated to create such hwpacks and linaro-media-create has been updated to use them.
http://
http://
l-m-c should have
--dev <boardname> where boardname is not in a hard coded list in l-m-c
--boot-loader <bootloader> where boot-loader also shoud be unknown to l-m-c
--probe-hwpack should provide info about what the hwpack supports
Using the --dev option to select appropriate parts of the hwpack metadata would also solve the OneHardwarePack
This would still not reduce maintenance of l-a-m-c which does not use hwpacks.
