From e11db644884242795b01ea10e2949f2f56005b0b Mon Sep 17 00:00:00 2001 From: Sam Protsenko Date: Sat, 25 Oct 2025 20:06:58 -0500 Subject: [PATCH] mmc: exynos_dw_mmc: Disable FMP for Exynos850 chip Add DWMCI_QUIRK_DISABLE_FMP flag to Exynos850 driver data to make the driver disable FMP in case of Exynos850 chip. That makes eMMC on Exynos850 functional when U-Boot is executed during USB boot.
