One more thing, if you want to make things bisectable patch 6 ("mtd: fix build issue with includes") and it's fixup should be squashed in patch 5 ("mtd: add get/set of_node/flash_node helpers"), because the build failure you're fixing in patch 6 is introduced by patch 5. > > [1] https://travis-ci.org/openedev/u-boot-amarula/jobs/411596814 You mean [1]https://github.com/bbrezillon/u-boot/commits/wip-spi _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
