MTD support build wrong

You need to learn flash programmer before using mtd.

First, resize your cfi flash to 4M base addr 0 ,in sopc builder, and regenerate sof.

Then enable epcs mtd and cfi mtd,

in drivers/mtd/maps/

edit epcs_map.c

static struct mtd_partition epcs_partitions =
{
    {
  .name = "sof_kernel",
  .size = 0x200000,
  .offset = 0x000000,
    }
};
static const char *part_probes __initdata = {NULL};

edit altera.c

static struct mtd_partition alteramap_partitions = {
    {
  .name =  "romfs/jffs2",
  .size =  0x400000,
  .offset =    0x000000,
    }
};

Rebuild kernel image from the start "make clean", "make linux_hwselect...."....
