U-Boot on this board grew a long time ago past the 384 KiB that
it reserves for the U-Boot image, before the environment.  Thus,
saveenv overwrites the U-Boot image and bricks the board.

I tried to find out when U-Boot grew beyond this point, but there is a
long stretch in the history where this board did not build -- and
AFAICT when it did fit in 384 KiB, it was missing vital features such
as fdt support.  Turning off CONFIG_VIDEO was not enough to make it
fit.  Thus, I don't think we have any choice other than to move the
environment.

U-Boot does not have system calls (the services it exposes to
standalone commands use a different mechanism), so the syscall handler
is dead code.  It's also broken code, as it assumes it is located at
0xc00 -- while even before the patch to stop relocating exception
vectors to 0, U-Boot had the syscall at 0x900.

The critical and machine check return paths are never called -- the
regular exception return path is used instead, which works because
xSRR0/1 have already been saved and can be restored via the regular
SRR0/1 (we don't care too much in U-Boot about taking a critical/mcheck
inside another exception prolog/epilog).

Also remove a few other small unused functions.

Booke does not require exception vectors to be located at address zero.
U-Boot was doing so anyway, simply because that's how it had been done
on other PPC.  The downside of this is that once the OS is loaded to
address zero, the exception vectors have been overwritten -- which
makes it difficult to diagnose a crash that happens after that point.

The IVOR setup and trap entry code is simplified somewhat as a result.

Also, there is no longer a need to align individual exceptions on 0x100
byte boundaries.

QEMU 2.3 changes the address layout of the CCSR map in the PV ppce500 machine
to reside in higher address space.

Unfortunately, this exposed a glitch in u-boot for ppce500: While providing
a function to dynamically evaluate the CCSR region's position in physical
address space, we never used it. Plus we forgot to support 64bit physical
addresses.

This patch fixes that mishap, making u-boot work fine with latest QEMU again.

According to the MPC8555/MPC8541 reference manual the SS_EN (source
synchronous enable) bit in the DDR_SDRAM_CLK_CNLT register must be set
during initialization.

>From section 9.4.1.8 of that manual:

   Source synchronous enable. This bit field must be set during
   initialization. See Section 9.6.1, "DDR SDRAM Initialization
   Sequence," details.

   0 - Reserved
   1 - The address and command are sent to the DDR SDRAMs source
       synchronously.

In addition, Freescale application note AN2805 is also very clear that
this bit must be set.

This patch reverts a change introduced by commit
457caecd.

Testing Done:

Compiled targets CONFIG_TARGET_MPC8555CDS and CONFIG_TARGET_MPC8541CDS
and inspected the generated assembly code to verify the SS_EN bit was being
set.  There is one extra instruction emitted:

  fff9b774: 65 29 80 00  oris    r9,r9,32768

Compiled the CONFIG_TARGET_MPC8548CDS target and verified that no
additional instructions were emitted related to this patch.

Booted an image on a MPC8541 based board successfully.

When told to keep outputs, be much more liberal in what files we keep.
In addition to adding 'MLO', keep anything that matches u-boot-spl.* (so
that we keep the map file as well) and anything we generate about
'u-boot itself.  A large number of bootable formats now match this and
thus it's easier to build many targets and then boot them afterwards
using buildman.

At present buildman tries to detect an aborted build and doesn't record a
result in that case. This is to make sure that an abort (e.g. with Ctrl-C)
does not mark the build as done. Without this option, buildman would never
retry the build unless -f/-F are provided. The effect is that aborting the
build creates 'fake errors' on whatever builds buildman happens to be
working on at the time.

Unfortunately the current test is not reliable and this detection can
trigger if a required toolchain tool is missing. In this case the toolchain
problem is never reported.

Adjust the logic to continue processing the build result, mark the build as
done (and failed), but with a return code which indicates that it should be
retried.

The correct fix is to fully and correctly detect an aborted build, quit
buildman immediately and not write any partial build results in this case.
Unfortunately this is currently beyond my powers and is left as an exercise
for the reader (and patches are welcome).
