[U-Boot] [PATCH v2 1/2] arm: ls1021aqds: Convert to driver model and enable serial support

York Sun york.sun at nxp.com
Mon Feb 22 20:01:10 CET 2016


Split duart configuration as device tree file. Move /chosen node
out of board commone device tree. Convert ls1021aqds nor and SD
configurations to driver model support (qspi already uses DM).
Enable ns16550 DM serial driver for nor configurations.
