From: "Lan Yixun (dlan)" <dennis.y...@gmail.com>
The problem here is that uboot can't mount ext4 filesystem with
commit "50ce4c07df1" applied. We use hard-coded "SECTOR_SIZE"(512)
before this commit, now we introduce (block_dev_desc_t *)->log2blksz
to replace this macro. And after we calling do_ls()->fs_set_blk_dev(),
the variable log2blksz is not initialized, which it's not correct.
And this patch try to solve the problem by caculating the value of
log2blksz from variable blksz.

the console output after commit "50ce4c07df1" applied:
lt703a # ext4ls nand 3:0
Failed to mount ext2 filesystem...
** Unrecognized filesystem type **
