### 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 enabled ADK_KERNEL_* vars into
# .kernelconfig.kernel
# 2) get the global and device-specific static kernel config and place it into
# .kernelconfig.board
# 3) append ${FS_CMDLINE} to the kernel commandline inside .kernelconfig.board
# 4) merge both together into .kernelconfig.tmp
# 5) 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)
# 6) remove the temporary .kernelconfig.tmp
###
