Testing the written sequence with logs are more authentic than listing on a driver file. > * > * SPDX-License-Identifier: GPL-2.0+ > */ > -- > 2.1.1 > thanks! -- Jagan. _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
