When using the options EXTERNAL_KERNEL_TREE or KERNEL_GIT_CLONE_URI,
the command "make downloads" fails as it tries to download the kernel
tarball despite the option. This doesn't happen during a regular build
as in that case, the dependency is conditionned through the LINUX_SITE
variable, which is not set in these cases.

Below is a snapshot of the error for an target using a 3.14 kernel:

make[3]: *** No rule to make target `.../dl/linux-3.14.tar.xz',
needed by `download'.  Stop.

GNU grep has a high per-expression setup overhead when compiling regular
expressions. Use -F to force it to interpret the input as fixed strings,
which is much faster (fraction of a second instead of multiple minutes).

If initramfs is enabled, build a second pass kernel containing the CPIO
rootfs, preliminary work to get non exclusive enabling of initramfs.

in combination with kernel symbol export stripping this significantly reduces
the kernel image size

kernel-build.mk: there is no tarball when using CONFIG_KERNEL_GIT_CLONE_URI or CONFIG_EXTERNAL_KERNEL_TREE, do not make the prepared stamp file depend on it in this case

SVN-Revision: 28361

- support kernel config overlays in env/
- allow overriding the target kernel config with CONFIG_TARGET=platform|subtarget|env

SVN-Revision: 26498

SVN-Revision: 22518

add a build system option for collecting all kernel debug information (including modules) in a tarball

SVN-Revision: 22327

Revert "sort Kconfig symbols automatically to make Kaloz happy :p" Relying on some sort implementations' weird behaviour of ignoring # and whitespaces at the beginning of a line is not a good idea, and it's certainly not portable

merge target kernel config files with subtarget config files and add a variable override for editing the target kernel config file with make kernel_menuconfig in case the subtarget contains overrides (thx, sn9)

rework parallel building to get rid of some warnings and add back support for parallelizing the kernel build fixes #3882

SVN-Revision: 12322

create a platform config-* file if there is none already when running kernel_menuconfig or kernel_oldconfig

large improvement for parallel builds. works without V=99 now and without warnings. tested with -j on an 2x dual core opteron machine

major target cleanup. it is now possible to have subtargets that can override many target settings, including arch - merge adm5120, adm5120eb. target profiles still need to be adapted for subtargets

SVN-Revision: 8694

strip the kernel version suffix from target directories, except for brcm-2.4 (the -2.4 will be included in the board name here). CONFIG_LINUX_<ver>_<board> becomes CONFIG_TARGET_<board>, same for profiles.
