	help
	  This option will re-use the same kernel sources as the one
	  that have been used for the kernel headers of the
	  cross-compiling toolchain. Having the same version for the
	  kernel running on the system and for the kernel headers is
	  not a requirement, but using the same version allows to
	  download only one tarball of the kernel sources.

config BR2_LINUX_KERNEL_CUSTOM_VERSION
	bool "Custom version"
	help
	  This option allows to use a specific 2.6.x or 2.6.x.y
	  official versions, as available on kernel.org

	  This option allows to specify the http or ftp location of a
