We do not need to manually set mini.config file anymore.
Every target system, even Qemu emulating different models get
it its own. Cleaner and simpler to add new targets.

Instead of maintaining mk/modules.mk which defines compilations of
related kernel modules to pack together into a single package, follow an
automatic approach: For every kernel module found in the modules
installation directory, create a single package.
There are a few caveats to cover:
=== Module Loading Order ===
Upon bootup, module loading is ordered based on the number-prefixed
files in /etc/modules.d/. The correct number was previously managed in
mk/modules.mk on a per-collection basis. The new approach is to have
levels which modules are to be assigned to. Level 0 contains modules
with no dependencies at all. Level 1 contains modules which have only
level 0 dependencies, and so on. This information is determined at
compile-time by make-module-ipkgs.sh.
=== Module Installation to Target RootFS ===
Since module packages are created automatically from the modules the
script finds, ADK build system has no knowledge about the connection
between what the user has selected in menuconfig and the actual module
packages. Therefore the earlier approach to install selected packages
into rootfs does not hold anymore. Instead, use wildcards to find all
packages in firmware directory prefixed by 'kmod-' and install them all
(hopefully doing the right thing).
=== Kernel Version ===
KERNEL_VERSION now contains KERNEL_RELEASE already
By creating a localversion file, make KERNEL_RELEASE part of the
kernel's version number (so KERNEL_VERSION is correct in most
situations)

Qemu emulates a Coldfire Evaluation board without MMU.
As that is the first non-MMU platform in OpenADK I added
ADK_TARGET_UCLINUX. Mksh can not be used for non-MMU, because
it requires fork() for job control and other things.
We use hush here. non-MMU support in uClibc does not have
shared library support.
Kernel does not start yet. So no runtime testing, but at least
coldfire toolchain can be tested with uClibc-ng.

to avoid namespace collisions in some packages, rename TOPDIR.
Sorry you need to make cleandir && make prereq && make
|
|
cleanup target/*/Makefile stuff.

disable systems without thread local storage, not supported by
OpenADK anymore. Remove m68k uclibc. fix kernel bootup in aranym.
|
|
only miniconfig is used for all targets.
aranym support is still broken/experimental.
32 bit kernel support for 64 targets need to be fixed.
tested on usb boot on ibm-x40
