Subject: mmc: exynos_dw_mmc: Disable FMP for Exynos850 chip
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=e11db644884242795b01ea10e2949f2f56005b0b;p=thirdparty%2Fu-boot.git

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.
