I'm looking for some information and/or some hardware in this installment.
Today, I noticed that the SD 2.0 specification has been released by the SD association. The simplified version, that is. The full spec, like the 1.x versions, doesn't include the security features. Looks like there's a number of new 'host' requirements. I can't yet deside if these requirements are at a hardware or a software level yet...
So, if someone wants to purcahse me a 8GB SD or MMC card, I'll be happy to make it work.
I've started in earnest on the mmc layer. It should be done shortly. The qdmmc driver that Bernd wrote lead the way, but making commands properly be async was difficult in its structure, so I've decided to try it with the proper layering instead.
