+### Kernel .config Creation
+# The following target combines all kernel-related variables and
+# config files into a single one to be used as the final kernel
+# configuration when building. This is how it's done:
+# 1) fetch all ADK_KPACKAGE_KMOD_* vars into 
+#    .kernelconfig.modules and set them to "m"
+# 2) fetch all enabled ADK_KERNEL_* vars into
+#    .kernelconfig.kernel (no conversion, as they are booleans)
+# 3) repeat 2) for the disabled ones and save them into
+#    .kernelconfig.nokernel (to overwrite defaults)
+# 4) get the device-specific static kernel config and place it into
+#    .kernelconfig.board
+# 5) prepare for merging:
+#    * if a variable is disabled in .kernelconfig.board and
+#      enabled in either of .kernelconfig.{modules,kernel},
+#      remove it from .kernelconfig.board
+#    * append ${FS_CMDLINE} to the kernel commandline inside
+#      .kernelconfig.board
+# 6) merge (cat) it all together into .kernelconfig.tmp
+# 7) check if .kernelconfig.tmp differs from the current one
+#    (.kernelconfig) at all, overwriting the current one
+#    only if it does (so the timestamp stays intact)
+# 8) remove the temporary .kernelconfig.tmp
