- Move oob layout to driver
- make hwecc support nonoptional but selectable by the board.
- let the boards decide which buswidth / ecc type to use. They know
better than the user which gets confused by too many kconfig options.
- Let the boards explicitly register the nand device.
I tried to seperate this further, but failed because of too many dependencies
in the code.

The board code or startup script should enable it when
it actually wants to.

Similar to ac2d4d71ba, copy the behaviour
from Linux which does:
cfi_send_gen_cmd(0x80, cfi->addr_unlock1, chip->start, map, cfi, cfi->device_type, NULL);
Notice the third parameter which is simply chip->start. Needed for some
SST-flashes.

Change device parameters so that the memory management is in generic
code. This also removes the need of storing statically initialized
parameters as they are stored in a struct list_head for each device.

While at it remove some unused code and an unbalanced

Copy the behaviour from Linux which does:
cfi_send_gen_cmd(0xAA, cfi->addr_unlock1, chip->start, map, cfi, cfi->device_type, NULL);
...
(Notice the third parameter which is simply chip->start).
Solves erase problems with SST flashes.

This patch allows using the i.MX (LCDC) framebuffer driver on boards
using an i.MX21 SoC.

For some weird reason this fixes nand boot on i.MX21. Since
interrupts are globally disabled it doesn't hurt on other
SoCs.

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.

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.

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.
