OpenBSD's sdmmc(4) for NetBSD

$Id: sdmmc.html,v 1.6 2006/08/29 04:11:49 uebayasi Exp $

This is OpenBSD's sdmmc(4) - SD/MMC card driver, ported to NetBSD. This is supposed to work on standard SD host controllers, like Ricoh 0x822 bridge. I'm using this on DELL Inspiron 9300.

This port uses scsipi(4) to represent itself as a block device. This is how the original OpenBSD code does, but this is very probably _not_ the best way.

(Note that my port is pre-alpha quality!)

Installation

1. % cd /usr/src/sys
2. % pax -rzvf sdmmc-20060718.tar.gz
3. % gzip -cd sdmmc-20060718.patch.gz | patch -p0

TODO

• Reconsider not to emulate SCSI device using scsipi(4), but be a real block device?
• Clean up config(9); don't always attach scsipi(4) bus.
• Catch up with the latest code in OpenBSD.
• Redo sdhc PCI configuration / detection.
