Fri Apr 14 01:11:24 UTC 2017
The device tree source files of at91sam9263ek boards are copied from
the Linux v4.10, do the changes as below.
- Add the reg property for the pinctrl node.
- Move the gpio (pioA, pioB, pioC, pioD, pioE) nodes as the pinctrl's
slibling nodes, instead of the child nodes.
- Add the "u-boot,dm-pre-reloc" property for the dbgu node are used
in board_init_f stage.
- Fix the compilation warnings.

Changes in v2:
- Rebase on the master branch (22e10be45) of u-boot-dm git tree.
