Testing with A10 Gemei G9 Tablet, FEL mode is broken:

a) With usb-boot via fel:

I get following error/warning: 
Loading Environment from FAT... Card did not respond to voltage select!

=> mmc list
mmc at 1c0f000: 0
### All commands below stalls for a bit (~2 seconds), but return nothing
=> mmc info  
=> mmc dev 0
=> mmc part

b) When booting from SD-card [1], card is properly found, identified and
even partitions are there.

dd if=u-boot-sunxi-with-spl.bin of=/dev/mmcblk0 seek=8 bs=1024
