[U-Boot] [PATCH v5 1/3] configs: at91sam9x5ek: Update to support DM/DT

Tue Apr 18 06:51:54 UTC 2017

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.

Changes in v5:
 - Adjust CONFIG_ENV_OFFSET for NAND to avoid the conflict caused
   by the increased binary size.

Changes in v4: None
Changes in v3:
 - Convert Atmel mci driver to support the driver model.
 - Remain the SPI_SPEED macro.
 - Add the support of Atmel uart device be used in the
   board_init_f stage.
 - Disable the SPL for nand config.
 - Improve the commit log.

Changes in v2: None
