"cache" on the MTD device is a yaffs2 filesystem mounted under /cache. "boot" and "recovery" are the boot and recovery images in the regular Android boot image format.

On the eMMC device, "system" is /system, "userdata" is /data, and "media" is /sdcard.

No mmcblk*boot* devices -- here are the entire contents of /dev/block:
