From caf7eb1ca514b0e95ecd5d053d905ef211f2afa9 Mon Sep 17 00:00:00 2001 From: Tibault Damman Date: Tue, 15 Sep 2020 15:04:14 +0200 Subject: [PATCH] package/freescale-imx/firmware-imx: custom padding Some derivatives (such as Variscite imx8mm) expect the (LP)DDR4 training data to be padded to a different length. eg: https://github.com/varigit/uboot-imx/commit/5f8d814f This patch makes the padding length configurable.
