This change is an adaptation of commit 81e8a52e8e40e47 from poky/master. Linux kernel build dependencies include bison since v4.16. There were two different commits in poky adding those dependencies: - poky/master: 81e8a52e8e40e47 - poky/sumo: 20e4d309e12bf10 However just adding bison-native to DEPENDS in linux or linux-yocto class (as in poky/sumo) appears to be insufficient. The reason has been clarified in 81e8a52e8e40e47 commit message: "For linux-yocto, we also need to specify the compiler/tools dependencies for the configme task since it executes before configure and hence the main kernel build DEPENDS will not always be in the sysroot before it executes. Without those dependencies the kernel will be incorrectly configured (i.e. bison is missing) or the configuration will fail the mitigation tests." Layer meta-sunxi is compatible with multiple Yocto releases. Some of those releases have been developed and tested with earlier kernels. So they may not include new bison kernel build dependencies. That is why it makes sense to specify new kernel build dependencies explicitely in meta-sunxi kernel recipes rather than rely upon upper layers. Signed-off-by: Sergey Matyukevich <geomatsi@gmail.com>
