meta-swupdate, Yocto layer for deploy tool
==========================================
This layer's purpose is to add support for a deployment
mechanism of Yocto's images based on swupdate project.
Layer dependencies
------------------
This layer depends on:
URI: git://github.com/openembedded/meta-openembedded.git
subdirectory: meta-oe
BitBake variable expansion
--------------------------
To insert the values of BitBake variables into the update file, pre- and postfix
the names with "@@". For example, to automatically set the version tag, use the
line `version = "@@DISTRO_VERSION@@";` in your sw-description file.
Image hashing
-------------
During creation of the update file, occurrences of @IMAGE (where IMAGE is an
image filename) are replaced with the sha256 hash of the image.
SWU image signing
------------
There are 3 signing mechanisms supported by meta-swupdate at the moment:
1. RSA signing:
* Set variable: `SWUPDATE_SIGNING = "RSA"`
* Set `SWUPDATE_PRIVATE_KEY` to the full path of private key file
2. CMS signing:
* Set variable: `SWUPDATE_SIGNING = "CMS"`
* Set `SWUPDATE_CMS_CERT` to the full path of certificate file
* Set `SWUPDATE_CMS_KEY ` to the full path of private key file
3. Custom signing tool:
* Set variable: `SWUPDATE_SIGNING = "CUSTOM"`
* Set variable `SWUPDATE_SIGN_TOOL' to custom string that needs to be
executed in order to perform the signing
sw-description is signed and the signature is written to sw-description.sig
which is included in the SWU file.
Encrypted private keys are not currently supported since a secure
mechanism must exist to provide the passphrase.

Submitting patches
------------------
You can submit your patches (or post questions reagarding
this layer to the swupdate Mailing List:
swupdate@googlegroups.com
When creating patches, please use something like:
git format-patch -s --subject-prefix='meta-swupdate][PATCH'
Please use 'git send-email' to send the generated patches to the ML
to bypass changes from your mailer.
