I have put external pullups on marsboard, boot from sd. Linux kernel init emmc fine, 4-bit width bus, so board works well
Hit any key to stop autoboot: 2 ... 0
=> mmc list
SUNXI SD/MMC: 0 (SD)
SUNXI SD/MMC: 1
=> mmc dev 0
switch to partitions #0, OK
mmc0 is current device
=> mmc part

## Unknown partition table type 0
When i try to boot from emmc still has error

emmc burned with same image as sd card, with mbr. rootfs, etc..
linux booted from sd card, well works with emmc partitions
