- ### 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
