Yes. If you can do that, it's helpful to me for reviewing. :)

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.
