[U-Boot] [PATCH v3 0/3] board: at91sam9x5ek: Convert to support DM and DT
The purpose of the patch set is to convert the board to support the driver model and device tree. It is based on the patch set: [PATCH v8 0/2] pinctrl: at91: Add pinctrl driver https://lists.denx.de/pipermail/u-boot/2017-March/284577.html
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. - Remove Atmel mci related code. - Use CONFIG_DEBUG_UART_CLOCK as the input clock for the early debug UART. - Drop [PATCH 4/5] configs: at91sam9x5ek: move SYS_NO_FLASH to defconfig.
Changes in v2: - Rebase on the patch set: [RESEND PATCH v2] ARM: at91: add default config file for sama5d36ek CMP board http://lists.denx.de/pipermail/u-boot/2017-February/280525.html
Wenyou Yang (3): configs: at91sam9x5ek: Update to support DM/DT board: at91sam9x5ek: Clean up code board: at91sam9x5ek: 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.
