### 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",
# fetch all ADK_KERNEL_MOD_* 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
