Hi! Very appreciate your help! Hope we will fix it, because my board will be garbage without emmc ( So, my steps:
git clone git://git.denx.de/u-boot.git --depth 1; cd u-boot; make CROSS_COMPILE=arm-linux-gnueabihf- A20-OLinuXino-Lime_defconfig make CROSS_COMPILE=arm-linux-gnueabihf-
Also turn on CONFIG_MMC_TRACE
After run, got:

So, spl_mmc.c on line 66, blk_dread return 0 count blk.h on line 389, block_dev->block_read(block_dev, start, blkcnt, buffer) return 0 block_dev->block_read is a pointer, seems like it defined in mmc_legacy.c on line 144, bdesc->block_read = mmc_bread; mmc.c, line 285 mmc_read_blocks return Failed to read blocks mmc.c, line 223, mmc_send_cmd return 0, cmdidx was 17, like last in mmc trace

Emmc Card was the new one, so i just burn a dump of working sd. Previously sd have been wired to board for test.
Board is a custom, like olinuxino lime which with nand and sd slot, 512 mb ram. So i using it defconfig and in case of sd card, it works. Emmc lines has external pullups according to the datasheet.
Well, i needs to get more information..If you guess that seems to return 0 from block_read().. then you can find which condition was hit..is it impossible?
If you can share more debug message..then i will help you.

Like a sd card. I have emmc to sd adapter, so
dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8
I guess you cleaned[1] the card before doing this?
and then just solder emmc to my board.
OK, which a20 board?
