[U-Boot] [bug report] sunxi: booting from eMMC

[Alexandr Bochkarev]

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:

hdr read sector 80, count=0
mmc_load_image_raw_sector: mmc block read error
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###

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
