This patchset is used for hs200/hs400/ddr52 mode of eMMC device, and fixes some bug for dw_mmc & sdhci controller. It's only valid in U-Boot stage, we still use 'High Speed' in SPL. I tested it on evb-rk3288 board(eMMC 4.5) and evb-rk3388 board(eMMC 5.0). > > I just reviewed an MMC series at add higher speed support. I'm not > sure but I suspect these overlap. Ha, I just reviewed Vignesh's patches, it focuses on uhs mode of sd card. It looks to me. But some details are not the same as mine. Anyway, what do you think? > > Regards, > Simon > > >
