Ah, yes.  I can also see the problem here after turning on
DEBUG_SPINLOCK.

Ah, okay. After turning it off, it works a lot better :)

That doesn't mean the problem is fixed. [...]

Yes, I know that. I should have put the 'works' above in quotes, sorry.

MMC fails for me (note: the card works fine with an mx35-based board)

	mmc0: new high speed MMC card at address 0001
	mmcblk0: mmc0:0001 AF HMP 247 MiB 
	mmcblk0: retrying using single block read
	mmcblk0: error -84 transferring data, sector 0, nr 8, card status 0x900
	end_request: I/O error, dev mmcblk0, sector 0

EILSEQ means CRC failure.  Probably unrelated.

Even if it works in another setup? As a result of the above, I can't read the
partition table of that MMC. The mx35 can do so.

SDIO card locks the machine. Is it supposed to work already?

Guess it's the spinlock causing that problem.

Yeah, that could be. In addition, I was just generally interested if SDIO has
been tested by Shawn.
