[GSoC 2018]:SDHCI MMC Driver | Haiku Project

qemu is not hard to test at all. In fact it is common to use it when writing drivers, because you can build on your host system and test in a VM very easily.

I do have one such laptop but it is used for other purposes currently. And it is about 10 years old. All other laptops I owned since then use an USB based SD card reader.
