This patch series adds support SD3.0 and eMMC HS200 modes for ZynqMP. This series also contains changes in mmc and sdhci framework to support SD3.0 and HS200.
Split the patches as mmc side and sdhci side..after that, i will review each patches.
Do you mean to split changes of mmc.c and sdhci.c separately? if so, will do that.
Yes. If you can do that, it's helpful to me for reviewing. :)
And did you consider about accessing to boot partition? As i know, boot partition can't support HS200.
No, didn't consider that yet.
Maybe..It needs to consider about this case..because we can access to boot partition with boot command. I think it's not difficult. When switch the partition, checking the speed mode and if mode is HS200, switch to DDR50 or SDR50..etc.
Anyway, Thanks for working this. I will wait for your next patches.
