Linux kernel module for Alcor Micro AU6601 Secure Digital Host Controller plus concerning ebuild for gentoo, Unfortunately this kernel module doesn't work with newer kernels-- so I have to use ampe_stor instead. ...
This driver is based on documentation which was based on my RE-work and comparision with other MMC drivers. It works in legacy mode and can provide 20MB/s R/W spead for most modern SD cards, even if at least 40MB/s should be possible on this hardware. It was not possible provide description for all register. But some of them are important to make this hardware work in some unknown way.
Biggest part of RE-work was done by emulating AU6601 in QEMU.
