The device tree source files of at91sam9x5ek board are copied from the Linux v4.10, do the changes below. - Add the reg property for the pinctrl node. - Move the gpio (pioA, pioB, pioC ...) nodes as the pinctrl's slibling nodes, instead of the child nodes. - Add the "u-boot,dm-pre-reloc" property to determine which nodes are used by the board_init_f stage. - Change the compatible of the spi flash to "spi-flash". - Add the spi0 aliases. - Fix the compilation warnings.
