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.

CRC is generated to protect the link between the card and the host.  It
means that the CRC computed by the card for the transfer and the CRC
computed by the host didn't match.

In other words, data was corrupted in some way between the card and the
MMC host.
