[U-Boot] [PATCH v5 2/6] board: sama5d3xek: Clean up code

Wenyou Yang wenyou.yang at atmel.com
Fri Apr 14 00:51:43 UTC 2017


Due to the introduction of the pinctrl and clk driver, and using
device tree files, remove the unneeded hardcoded pin configuration
and clock enabling code from the board file.
