5541543f68 configs: at91: Remove CONFIG_SYS_EXTRA_OPTIONS assignment
To remove the assignment of CONFIG_SYS_EXTRA_OPTIONS option,
which is deprecated, use the CONFIG_XXXX_BOOT options to
indicate the boot media, and the SoC is selected by the board.

31f8d39e2a board: atmel: use get_nand_dev_by_index()
As part of preparation for nand DM conversion the new API has been
introduced to remove direct access to nand_info array. So, use it here
instead of accessing to nand_info array directly.

0ab5433da2 configs: at91sam9n12ek: Update for DT and DM support
Update the configuration files to support the device tree and driver
model. The device clock and pins configuration are handled by the
clock and the pinctrl drivers respectively.

Because the limitation of internal SRAM size, the SPL with driver
model can't be supported, disable the SPL option.

2dc63f7367 gpio: at91_gpio: remove CPU_HAS_PIO3 macro
The intention of the removal is the preparation to introduce the
new AT91 PIO pinctrl driver.

Use the union to make the PIO3 and PIO2's registers be together
and make their offset aligned.

b616d9b0a7 nand: Embed mtd_info in struct nand_chip
nand_info[] is now an array of pointers, with the actual mtd_info
instance embedded in struct nand_chip.

This is in preparation for syncing the NAND code with Linux 4.6,
which makes the same change to struct nand_chip.  It's in a separate
commit due to the large amount of changes required to accommodate the
change to nand_info[].

The mpddr.c depends on ATMEL_BASE_MPDDRC for the base address to configure the controller.

b899fa3901 arm: at91sam9n12: change EBI IO to high drive mode
As both the DDR SDRAM and NAND flash connect to EBI on at91sam9n12
and share the lower 8 bits data line. If use low drive of the data
line, it will cause DDR data access corrupt in lower address, so
change the data line to high drive mode

This will fix the Linux kernel boot issue when use Lower address
