Add a script which can be used to verify that the non-conditional config fragments are consistent, i.e. none of them disappear when merged into an an allnoconfig. Change-Id: I390823ead7ca5540f969a73e641855b8d9f55008 Signed-off-by: Steve Muckle <smuckle@google.com>

Usage: ${0##*/} [-h] [-a arches] [-v versions] -k path-to-kernel

|
Check that the kernel config fragments are consistent with the Kconfig files
|
|
in the given kernel versions. This requires an android common kernel repo to
|
|
be checked out and made available to this script via the -k option or the
|
|
KERNEL_PATH environment variable. Note this script does not verify the
|
|
configs in the conditional XML fragments.
