The original implementation select HS timing by default, add available type selection for higher speed mode compatibility, such as hs200, hs400, hs400es.
By the way, we assume that card run at 1.8V or 1.2V I/O when its timing is ddr52/hs200/hs400(es).

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?
I didn't review both yet..After checking, i will share my opinion. how about?
*ping*... Did you test this patchset on Samsung platform? As far as I know, Samsung SoCs also make use of dw_mmc and sdhci controllers.
some details are not the same as yours..but some points are duplicated. DWMMC and sdhci controller side are not duplicated..
As i am feeling..your patches are based on Linux kernel code..right?
Yup, the kernel's mmc driver is stabilized and it was tested on so many various boards. Simon had review Jean-jacques's patch, but a little glitch need to be debugged. So I should wait for him, and rebase?
