Newer Freescale 3-Stack development systems are equipped
with 64MiB of DDR2 SDRAM, instead of the 128MiB of mDDR SDRAM
with which earlier versions were shipped.

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).

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

Also, do not allow to continue barebox after returning from the
application since we don't know anything about the state we are in.

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.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
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.

v2: Do not exit from all scripts but only the current one
This fixes the case:
barebox:/ cat /test
if [ 0 = 0 ]; then
exit 1
fi
barebox:/ /test
barebox:/ echo $?
0
barebox:/
Also, remove code to not allow exit from main shell. The for(;;) loop
in common/startup.c will bring us back anyway.
