  6. ### Kernel .config Creation
  7. # The following target combines all kernel-related variables and
  8. # config files into a single one to be used as the final kernel
  9. # configuration when building. This is how it's done:
  10. # 1) fetch all enabled ADK_KERNEL_* vars into
  11. # .kernelconfig.kernel
  12. # 2) get the global and device-specific static kernel config and place it into
  13. # .kernelconfig.board
  14. # 3) append ${FS_CMDLINE} to the kernel commandline inside .kernelconfig.board
  15. # 4) merge both together into .kernelconfig.tmp
  16. # 5) check if .kernelconfig.tmp differs from the current one
  17. # (.kernelconfig) at all, overwriting the current one
  18. # only if it does (so the timestamp stays intact)
  19. # 6) remove the temporary .kernelconfig.tmp
