ok?
Hi Mark,
This diff seems to break things on my Lenovo Ideapad 100s. The 100s has
an internal eMMC and a microSD card slot. As far

Go for it. Havent' tested it myself but looks good and is a
very much needed enhancement.
I found one

The diff below implements some speedups for sdhc(4). In particular:
* Implement high speed mode
* Implement support for 4-bit and 8-bit busses
* Use DMA for block transfers
High speed mode and wider bus support are only used for (e)MMC for
now, but DMA support should benefit SD cards as well.
