	  Select the kernel version to get headers from.

	  The kernel headers must be at least as old as the oldest
	  kernel you intend to run on your target.

	  If you use Buildroot to build a kernel, then you can use
	  the sources from that kernel as source for the headers.

	  If you choose a custom version of the kernel headers, or
	  choose to use the same sources as the kernel, you'll have to
	  select (below) the series of that kernel, so that Buildroot
	  can show or hide packages that have strong requirements on the
	  kernel headers.

	help
	  This option allows you to use a specific official version from
	  kernel.org, like 2.6.x, 2.6.x.y, 3.x.y, ...

	  Note: you cannot use this option to select a _longterm_ 2.6
	  kernel, because these kernels are not located at the standard
	  URL at kernel.org. Instead, select "Custom tarball" and
	  specify the right URL directly.

config BR2_KERNEL_HEADERS_CUSTOM_TARBALL
	bool "Custom tarball"
	help
	  This option allows you to specify a URL pointing to a kernel
	  source tarball. This URL can use any protocol recognized by
	  Buildroot, like http://, ftp://, file:// or scp://.

	  When pointing to a local tarball using file://, you may want
	  to use a make variable like $(TOPDIR) to reference the root of
	  the Buildroot tree.

config BR2_KERNEL_HEADERS_CUSTOM_GIT
	bool "Custom Git repository"
	help
	  This option allows Buildroot to get the Linux kernel source
	  code from a Git repository.
