The recent change to move the .bss outside of the image gives older
binutils (ld from eldk4.1/binutils-2.16) some headache:
ppc_85xx-ld: u-boot: Not enough room for program headers (allocated 3, need 4)
ppc_85xx-ld: final link failed: Bad value
We workaround it by being explicit about the program headers and not
assigning the .bss to a program header.

* Move to using absolute addressing always. Makes the scripts a bit more
portable and common
* Moved .bss after the end of the image. These allows us to have more
room in the resulting binary image for code and data.
* Removed .text object files that aren't really needed
* Make sure _end is 4-byte aligned as the .bss init code expects this.
(Its possible that the end of .bss isn't 4-byte aligned)

The 8544 DS doesn't have any cacheable Local Bus memories set up. By mapping
space for some anyway, we were allowing speculative loads into unmapped space,
which would cause an exception (annoying, even if ultimately harmless).
Removing LBC_CACHE_BASE, and using LBC_NONCACHE_BASE for the LBC LAW solves the
problem.

This patch changes the return type of initdram() from long int to phys_size_t.
This is required for a couple of reasons: long int limits the amount of dram
to 2GB, and u-boot in general is moving over to phys_size_t to represent the
size of physical memory. phys_size_t is defined as an unsigned long on almost
all current platforms.
This patch *only* changes the return type of the initdram function (in
include/common.h, as well as in each board's implementation of initdram). It
does not actually modify the code inside the function on any of the platforms;
platforms which wish to support more than 2GB of DRAM will need to modify
their initdram() function code.
Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc

With the new LAW interface (set_next_law) we can move to letting the
system allocate which LAWs are used for what purpose. This makes life
a bit easier going forward with the new DDR code.

Many of the spd.h #includers don't need it,
and wanted to have spd_sdram() declared instead.
Since they didn't get that, some also had open
coded extern declarations of it instead or as well.
Fix it all up by using spd_sdram.h where needed.

With recent toolchain versions, some boards would not build because
or errors like this one (here for ocotea board when building with
ELDK 4.2 beta):
ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab]
For many boards, the .bss section is big enough that it wraps around
at the end of the address space (0xFFFFFFFF), so the problem will not
be visible unless you use a 64 bit tool chain for development. On
some boards however, changes to the code size (due to different
optimizations) we bail out with section overlaps like above.
The fix is to add the NOLOAD attribute to the .bss and .sbss
sections, telling the linker that .bss does not consume any space in
the image.

The old macros made it difficult to know what WIMGE and perm bits
were set for a TLB entry. Actually use the bit masks for these items
since they are only a single bit.
Also moved the macros into mmu.h out of e500.h since they aren't specific
to e500.

The RTC on the M1575 ULI chipset requires a dummy read before
we are able to talk to the RTC. We accomplish this by adding a
second memory region to the PHB the ULI is on and read from it.
The second region is added to maintain compatiabilty with Linux's
view of the PCI memory map.

if a board/$(VENDOR)/common/Makefile exists, build it.
also add the first such case, board/freescale/common/Makefile, to
handle building board-shared EEPROM, PIXIS, and MDS-PIB code, as
dictated by board configuration.
thusly get rid of alternate build dir errors such as:
FATAL: can't create /work/wd/tmp/u-boot-ppc/board/freescale/mpc8360emds/../common/pq-mds-pib.o: No such file or directory
by putting the common/ mkdir command in its proper place (the common
Makefile). Common bits from existing individual board Makefiles have
been removed.

The PCIe bus that the ULI M1575 is connected to has no possible way of
needing more than the fixed amount of IO & Memory space needed by the ULI.
So make it use far less IO & memory space and have it use the shared LAW. This
free's up a LAW for PCIe1 IO space. Also reduce the amount of IO space needed
by each bus.
