This commit was manufactured to restore the state of the 7.0-RELEASE image. MFp4: When querying the operating condition of SD cards (using the 2007-06-05T17:04:44Z Warner Losh imp@FreeBSD.org 2007-06-05T17:04:44Z urn:sha1:6634080beea417f2f3486a2b94c8a49899fd10dd application specific SEND_OP_COND (CMD55 + ACMD41), go ahead and allow 100 tries. This gives a timeout of a second rather than the ~100ms the old style produces. I've had one old 16MB SD card which needs the extra time. I've now had reports from the field that other cards need this too. Originally done at BSDcan 2007 while waiting to give my embedding madness minitalk.

It is unclear to me exactly what the license would be for, or why it might be required. Err on the side of caution and include this disclaimer so anybody deploying this code can judge for themselves. I have no further unformation about the details. First cut at making detach work. also add sdh as a possible mmc bridge. 2007-05-15T05:49:14Z Warner Losh imp@FreeBSD.org 2007-05-15T05:49:14Z urn:sha1:0e1466ac89d04507665ff51d1d263c2fc83f88c9 Submitted by: Andrea Bittau (Andrea may have updated patches, but I've tested these) Don't need mmc_mode ivar 2007-05-15T05:46:58Z Warner Losh imp@FreeBSD.org 2007-05-15T05:46:58Z urn:sha1:78f8edfb449cf010677ca05d3adc2da81039aaf3 Preliminary MMC stack.

At the present time, there's only one bridge driver for the ARM9 based Atmel AT91RM9200.
