From: Sumit Garg <sumit.g...@oss.qualcomm.com> 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.
