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