From 49cf3b29134cd9d0feac25999be966070972d3c0 Mon Sep 17 00:00:00 2001 From: Sumit Garg Date: Thu, 10 Apr 2025 13:30:26 +0530 Subject: [PATCH] qcom_defconfig: Disable MMC HS200 mode support Currently the msm_sdhci doesn't yet support DLL configurations which are required to enable bus speeds greater that 100MHz. So disable HS200 mode support as of now as it requires bus speeds of 200MHz. This should fix eMMC issues reported on RB1/RB2 although it should fix issues for all Qcom platforms but it's not seen there as mostly SD cards available don't support HS200 mode. The SD cards usually works in high speed mode whose performance remains unaffected by this change. It only affects RB1/RB2 as eMMC flash on these support HS200 mode but the U-Boot driver currently is incapable of supporting that.
