[denzil][PATCH 0/1] menuconfig fix for denzil

[Paul Eggleton]

Note that as noted in the patch this relies upon the task tainting
feature in bitbake; this will do nothing with versions of bitbake that
do not have that feature.


The following changes since commit 95756cfbb7a9348b23cb46a49a5509e57e973faf:

  valgrind: fix default.supp missing issue (2012-08-21 11:19:26 +0100)

[denzil][PATCH 1/1] classes/cml1: ensure -c menuconfig forces a rebuild next time

[Paul Eggleton]

Ensure the following results in the kernel being rebuilt, repackaged and
re-deployed in the final step:

bitbake virtual/kernel
bitbake -c menuconfig virtual/kernel
[ make changes to the kernel configuration and save ]
bitbake virtual/kernel

If there are no changes to the configuration saved, the rebuild will not
be triggered.

Note that this relies on a function recently added to BitBake and
requires full hashing (i.e. BB_SIGNATURE_HANDLER must be set to a
signature handler that inherits from BasicHash) - if this is not the
case or the function is not available in the version of BitBake being
used this change will do nothing.

Fixes [YOCTO #2256].
