  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 ADK_KPACKAGE_KMOD_* vars into
  11. # .kernelconfig.modules and set them to "m"
  12. # 2) fetch all enabled ADK_KERNEL_* vars into
  13. # .kernelconfig.kernel (no conversion, as they are booleans)
  14. # 3) repeat 2) for the disabled ones and save them into
  15. # .kernelconfig.nokernel (to overwrite defaults)
  16. # 4) get the device-specific static kernel config and place it into
  17. # .kernelconfig.board
  18. # 5) prepare for merging:
  19. # * if a variable is disabled in .kernelconfig.board and
  20. # enabled in either of .kernelconfig.{modules,kernel},
  21. # remove it from .kernelconfig.board
  22. # * append ${FS_CMDLINE} to the kernel commandline inside
  23. # .kernelconfig.board
  24. # 6) merge (cat) it all together into .kernelconfig.tmp
  25. # 7) check if .kernelconfig.tmp differs from the current one
  26. # (.kernelconfig) at all, overwriting the current one
  27. # only if it does (so the timestamp stays intact)
  28. # 8) remove the temporary .kernelconfig.tmp
