From 010e58d448d5cb184fc53d6bbb87deee3ce5b223 Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Sun, 8 Dec 2019 22:06:56 +0100 Subject: imx: Add support for i.MX28 based XEA board This patch introduces support for i.MX28 based XEA board. This board supports DM/DTS in U-Boot proper as well as DM aware drivers in SPL (u-boot.sb) by using OF_PLATDATA. More detailed information regarding usage of it can be found in ./board/liebherr/xea/README file.
