From ed9e9b2213b6fe09005349057afa33a044bdd4d3 Mon Sep 17 00:00:00 2001 From: Sean Anderson Date: Tue, 23 Nov 2021 15:03:42 -0500 Subject: [PATCH] mmc: fsl_esdhc_imx: simplify 64bit check for SDMA transfers [ fsl_esdhc commit da86e8cfcb03ed5c1d8e0718bc8bc8583e60ced8 ] SDMA can only do DMA with 32 bit addresses. This is true for all architectures (just doesn't apply to 32 bit ones). Simplify the code and remove unnecessary CONFIG_FSL_LAYERSCAPE. Also make the error message more concise.
