   9 ### Kernel .config Creation
  10 # The following target combines all kernel-related variables and
  11 # config files into a single one to be used as the final kernel
  12 # configuration when building. This is how it's done:
  13 # 1) fetch all ADK_KPACKAGE_KMOD_* vars into
  14 #    .kernelconfig.modules and set them to "m"
  15 # 2) fetch all enabled ADK_KERNEL_* vars into
  16 #    .kernelconfig.kernel (no conversion, as they are booleans)
  17 # 3) repeat 2) for the disabled ones and save them into
  18 #    .kernelconfig.nokernel (to overwrite defaults)
  19 # 4) get the device-specific static kernel config and place it into
  20 #    .kernelconfig.board
  21 # 5) prepare for merging:
  22 #    * if a variable is disabled in .kernelconfig.board and
  23 #      enabled in either of .kernelconfig.{modules,kernel},
  24 #      remove it from .kernelconfig.board
  25 #    * append ${FS_CMDLINE} to the kernel commandline inside
  26 #      .kernelconfig.board
  27 # 6) merge (cat) it all together into .kernelconfig.tmp
  28 # 7) check if .kernelconfig.tmp differs from the current one
  29 #    (.kernelconfig) at all, overwriting the current one
  30 #    only if it does (so the timestamp stays intact)
  31 # 8) remove the temporary .kernelconfig.tmp
