This patch introduces proper ARM vector handling for i.MX28 CPU. This issue
wasn't addressed because the interrupts weren't enabled on any ARMv5 core,
therefore the issue wasn't noticed earlier.
In previous implementation, the vectoring code used by i.MX28 CPU when an
exception happened was that of the SPL. With this change, the branch target when
an exception happens can be reconfigured by U-Boot.

The devkit8000 ships with either a 128MB or 256MB NAND chip. In
order for SPL to work with 256MB NAND CONFIG_SYS_NAND_5_ADDR_CYCLE
needs to be set. After talking with Scott Wood this should be
safe to set even for smaller NAND chips.

This enables Vpp and disables the flash protection on the

This reconfigures the EBI (External Bus Interface) on the
integrator so that chip select 1, handling the flash memory, is
set to writeable. Without this it is not possible for U-Boot to
access flash memory and it crashes on startup since CFI won't
work properly.
Since this is the first time we use the EBI, we create a header
file for its registers.

When booting from Flash, the Integrator remaps its flash memory
from 0x24000000 to 0x00000000, and starts executing it at
0x00000000. This ROM thus hides the RAM underneath and first
0x40000 bytes of the memory cannot be tested by get_ram_size().
So let's test from 0x40000 to the end of detected memory
instead.

The new IO FPGA implementation for Versatile Express contains an MMCI
(PL180) cell with the FIFO extended to 128 words. This causes the
read_bytes() function to go into an infinite loop; as it will wait for
for the half-full signal (SDI_STA_RXFIFOBR) if there are more than 8
words remaining (SDI_FIFO_BURST_SIZE), but it won't receive this signal
once there are fewer than 64 words left to transfer.
One possible fix is to add some build time configuration to change
SDI_FIFO_BURST_SIZE for the new implementation. However, the problematic
code only seems to exist as a small performance optimisation, so the
solution implemented by this patch is to simply remove it. The error
checking following the loop is also removed as this will be handled by
code further down the function.
