c11528083e mpc85xx: workaround old binutils bug
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.

f0ff885ca6 mpc85xx: Update linker scripts for Freescale boards
* 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)

9973e3c614 Change initdram() return type to phys_size_t
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
MPC8641HPCN.

859a86a25c 85xx/86xx: Move to dynamic mgmt of LAWs
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.

53677ef18e Big white-space cleanup.
This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

25eedb2c19 FSL: Clean up board/freescale/common/Makefile
Each file that can be built here now follows some
CONFIG_ option so that they are appropriately built
or not, as needed.  And CONFIG_ defines were added
to various board config files to make sure that happens.

The other board/freescale/*/Makefiles no longer need
to reach up and over into ../common to build their
individually needed files any more.

Boards that are CDS specific were renamed with cds_ prefix.

f69766e4b5 85xx: Add the concept of CFG_CCSRBAR_PHYS
When we go to 36-bit physical addresses we need to keep the concept of
the physical CCSRBAR address seperate from the virtual one.

For the majority of boards CFG_CCSBAR_PHYS == CFG_CCSRBAR

a30a549a35 Remove erroneous or extra spd.h #includers.
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.

c8c41d4a80 85xx: Use proper defines for PCI addresses
We should be using the _MEM_PHYS for LAW and TLB setup and not _MEM_BASE.
While _MEM_BASE & _MEM_PHYS are normally the same, _MEM_BASE should only
be used for configuring the PCI ATMU.

64134f0112 Fix linker scripts: add NOLOAD atribute to .bss/.sbss sections
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.

2146cf5682 Reworked FSL Book-E TLB macros to be more readable
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.
