[PATCH 0/5] Provides a framework and initial modules for initramfs

[Otavio Salvador]

This patchset adds a very flexible and powerful initramfs framework
together with a small set of modules using it. Please refer to each
commit for the respective documentation.

The following changes since commit fb642d21111691b9302e16e984aff9d8fb18c431:

  buildhistory bbclass: avoid absolute paths for files-in-image.txt to avoid diff churn when relocating TMPDIR (2011-12-06 14:40:00 +0000)

[PATCH 1/5] initramfs-base: provides the base for a modular initramfs

[Otavio Salvador]

Provides the API to be used by the initramfs module. The modules need
to provide the following functions:

 <module>_enabled : check if the module ought to run (return 1 to skip)
 <module>_run     : do what is need

Boot parameters are available on environment in the as:

 'foo=value' as 'bootparam_foo=value'
 'foo' as 'bootparam_foo=true'

Another possibility is to add hooks to be run before and/or after a
module to be run, allowing for fancy features as dynamic debug shells
and like.

[PATCH 2/5] initramfs-module-debug: add

[Otavio Salvador]

Adds support to dynamic debugging of initramfs using bootparam in
following format:

 - shell                 : starts a shell before and after each module
 - shell=before:<module> : starts a shell before <module> is loaded and run
 - shell=after:<module>  : starts a shell after <module> is loaded and run

 - shell-debug                 : run set -x as soon as possible
 - shell-debug=before:<module> : run set -x before <module> is loaded and run
 - shell-debug=after:<module>  : run set -x after <module> is loaded and run
