Thanks, after changing DS-2[6] to ON and DS-2[7] to OFF, dmesg reports
the following on insertion of a card in the SD/MMC slot (SDHI1):
mmc1: new SDHC card at address 1234
mmcblk0: mmc1:1234 SA04G 3.68 GiB
mmcblk0: p1
Oddly, the Android demo still reports no SD card though. I'll try a few
more things to try to get that working.
