mmc/sd drivers

[tj]

Where can the latest mmc drivers in the kernel source be located? I am 
not talking about mass-storage usb or pcmcia drivers. I downloaded 
2.2.26 and there is no drivers/mmc directory. Where can the mmc drivers 
be located from their original distribution point?

2.2 is old.

MMC is supported for example on sharp zaurus, look
there for sources. SD requires binary-only module. Avoid it.

Thats not completely true. Last weekend I was using a 512Mb SD card on my iPAQ 
5550 with the 2.4.19 hh36.9 kernel from Handhelds.org. It was rather slow 
access (playing mp3s directly off the sd card had problems with pauses), but 
did work. I haven't actually got around to building a kernel for an ARM 
machine yet, but if you need the source I suggest you look round 
handhelds.org.

AFAIK, only the MMC-like modes of the SD cards are supported. The driver can't 
handle encryption, paralel data transfer modes (using 4 bits at a time) or SDIO 
cards.
