This is really great, thanks.

I do wonder(I am fairly new to eMMC) about 512B emulation.
In mmc utils there is a:
mmc disable 512B emulation <device>
        Set the eMMC data sector size to 4KB by disabling emulation on 
<device>.

I am hoping 4K size will increase performance and reliability?
Could you add this feature too to your patch set?
