[U-Boot] [PATCH v4 0/3] board: at91sam9m10g45ek: Convert to support DM and DT
The purpose of the patch set is to convert the board to support the driver model and the device tree.
The patch set is based on the patch set: 1./ [PATCH v3 0/6] ARM: dts: at91: Add dts files for AT91 SoCs' boards https://lists.denx.de/pipermail/u-boot/2017-April/287845.html
Changes in v4: - Adjust CONFIG_ENV_OFFSET for NAND to avoid the conflict caused by the increased binary size. - Rebase on the master branch(ad46af0e76) of u-boot-dm git tree. - Update the cover-letter. - Add Reviewed-by tag
Changes in v3: - Rebase on the master branch (22e10be45) of u-boot-dm git tree. - Update the cover-letter.
Changes in v2: - Add the support of Atmel uart device be used in the board_init_f stage. - Remove unused LED feature. - Disable the SPL options. - Move out [PATCH] ARM: dts: at91: Add dts files for at91sam9m10g45ek. - Add [PATCH] board: at91sam9m10g45ek: Enable early debug UART

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.
