p1022ds: use weak CFI flash accessors when DIU is enabled
On the Freescale P1022, the DIU and the LBC share address pins, which means
that when the DIU is active (e.g. the console is on the DVI display), NOR flash
cannot be accessed. So we use the weak accessor function feature of the CFI
flash code to temporarily switch the pin mux from DIU to LBC whenever we want
to read or write flash. This has a significant performance penalty, but it's
the only way to make it work.
This change allows the 'saveenv' command to work when the video display is
enabled. Erasing flash and writing to flash (with the 'cp' command) works,
but reading from flash (with the 'md' and 'cp' commands) does not. Also, while
flash is being written, the video display will be blank.

- CONFIG_SYS_SCCR_PCIEXP1CM used to enable PCIE clock instead of

e300: increase CONFIG_SYS_BOOTMAPSZ to allow booting large kernels
Newer Linux kernels can overrun the initial memory window used for
booting with their BSS area. When this happens, they overwrite the FDT
and silently fail to boot.
On e300 CPUs, the Linux kernel uses an initial BAT covering the first
256MB of RAM. See arch/powerpc/kernel/head_32.S for details. Increase
the value of CONFIG_SYS_BOOTMAPSZ to accommodate the maximum value
allowed by Linux. This will allow very large kernels to boot.

ppc4xx: Cleanup of PVR detection code in cpu.c
This patch cleans the PVR detection code in check_cpu() up a bit.
Basically the strings are better seperated, resulting in an easier
to understand and maintain code version.
The #ifdef's couldn't be removed easily because of two reasons:
- Some SoC revisions have the same PVR, so need a way to differentiate
between those two SoC's.
- In some case statements registers only available in this SoC variant
are referenced.
Instead I moved the CONFIG_440 #ifdef a bit, so that 405 platforms don't
add this 440 detection code and vice versa. Resulting in this U-Boot
image size change:
405EX (Kilauea): 408 bytes less
440EPx (Sequoia): 604 bytes less
460EX (Canyonlands): 564 bytes less

For this the parameters needed to be changed. So I intentionally squashed
