Look like the issue with MMC - CMD18 making host->ioaddr as 0x0 by
means of busy state or something..due to which CMD12 is unable to
process.

Here is the full log[1], while reading the sectors mmc issue CMD16, 18
and 12 in sequence out-of-which 16 and 18 has processed with proper
ioaddr.

Does CMD18 resp MMC_RSP_R1,5,6,7 0x00000000 is proper?

Breaking log:
------------------
mmc_load_legacy sectors = 15906
blk_dread: Call read dev = 0xff716208, blkcnt = 0x0, start = 0x1000
CMD_SEND:16
                ARG                      0x00000000
Sending CMD16 0xff0c0000
                MMC_RSP_R1,5,6,7         0x00000000
CMD_SEND:18
                ARG                      0x00000000

                MMC_RSP_R1,5,6,7         0x00000000
CMD_SEND:12
                ARG                      0x00000000
Sending CMD12 0x0

Any help?
