Sascha Hauer d03831887e imx_nand: use memcpy for copying from/to buffer 
We do not need to use memcpy32 in read_buf/write_buf because
in these functions we only access SDRAM and not the internal SRAM
buffer.

Sascha Hauer d5578b8179 nand_imx: Speed up sequential read 
When reading a page from nand prefetch the next page afterwards to
keep the controller busy. This way we can improve sequential reading
from NAND which is the common case for barebox.

Sascha Hauer 9d9be6ba9b nand_imx: use optimized memcpy 
The internal SRAM buffer of the i.MX NAND controller does not
allow byte accesses. We use the memcpy32 function to handle this.
If we have assembler optimized string functions we can do better
because they won't do byte accesses when source and target are word
aligned.

Ivo Clarysse 512a1c80ce Fix nand_imx for i.MX21 
Recent changes to the nand_imx driver broke it for i.MX21 systems;
the i.MX21 NAND controller is more akin to the one in i.MX27/i.MX31,
than to the one in i.MX25/i.MX35.

Robert P. J. Day 9edcbdc9f3 NAND: Free asprintf()-allocated space upon mtd device deletion. 
Given that add_mtd_device() invokes asprintf() thusly:

  mtd->cdev.name = asprintf("nand%d", mtd->class_dev.id);
  ...
  mtd->param_size.value = asprintf("%u", mtd->size);
  ...
  mtd->cdev_oob.name = asprintf("nand_oob%d", mtd->class_dev.id);

make sure del_mtd_device() frees that in the reverse order.
