[Buildroot] [RFC] Review request for branch for-2011.08/bootloaders

Hello,

This is not a pull request. This is stuff I'm preparing for the next
Buildroot release, and which I'm posting now to let everybody now that
I'm working on this, and to get early comments. Feedback is therefore
very welcome.

Basically, the idea is that we have a package infrastructure, and
features such as Git/Mercurial download, or usage of an existing
source tree should be added at the level of the package infrastructure
and not specifically for each package.

Unfortunately, some of the packages that would most benefit from those
new infrastructure features are the bootloader and kernel, since it's
typically the software components that have to be modified/tuned
during the course of an embedded Linux project.

Therefore, this series converts all bootloaders makefiles and the
kernel makefile to the package infrastructure. It also does a few
other related things.

More improvements are probably needed at the infrastructure level
(like changing the BR2_PACKAGE_<pkg> test to know if a target needs to
be added to TARGETS or not), but hopefully, you'll get the general
idea and have some feedback/ideas.

Thanks for your review,

Thomas
