[U-Boot] [PATCH v2 0/3] board: at91sam9263ek: 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.
Changes in v2: - Add converting UART to support DM_SERIAL and used in the board_init_f stage. - Remove unused LED feature. - Improve the commit log. - Add [PATCH]: board: at91sam9263ek: Enable early debug UART. - Move out [PATCH] ARM: dts: at91: add dts files for at91sam9263ek.
Wenyou Yang (3): configs: at91sam9263ek: Update for DT and DM support board: at91sam9263ek: Clean up code board: at91sam9263ek: Enable early debug UART
