9b827cf172 Align end of bss by 4 bytes
Most of the bss initialization loop increments 4 bytes
at a time. And the loop end is checked for an 'equal'
condition. Make the bss end address aligned by 4, so
that the loop will end as expected.

8a490422be ADS5121: Fix NOR and CPLD ALE timing for rev 2 silicon
MPC5121 rev 2 silicon has a new register for controlling how long
CS is asserted after deassertion of ALE in multiplexed mode.

The default is to assert CS together with ALE.  The alternative
is to assert CS (ALEN+1)*LPC_CLK clocks after deassertion of ALE.

The default is wrong for the NOR flash and CPLD on the ADS5121.

This patch turns on the alternative for CS0 (NOR) and CS2 (CPLD)
it does so conditionally based on silicon rev 2.0 or greater.

f889265753 fix DIU for small screens
The DIU_DIV register is 8 bit not 5 bit. This prevented large DIV values
so it was not possible to set a slow pixel clock and thus prevented
display on small screens.

board/ads5121/iopin.c
    Replace bit fields in struct iopin_t with a single
    field and intialize it via plain old macros.
    This fixes the type pun warnings and makes the code
    more readable.

board/ads5121/ads5121.c
    Add include iopin.h to ads5121.c for the iopin_initialize
    prototype.

    Add an extern void ads5121_diu_init(void)

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.

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.

5f91db7f58 MPC5121e ADS PCI support take 3
Adds PCI support for MPC5121

Tested with drivers/net/rtl8139.c

Support is conditional since PCI on old silicon does not work.

ads5121_PCI_config turns on PCI

In this version, condition compilation of PCI code has been moved
from ifdef in board/ads5121/pci.c to board/ads5121/Makefile as
suggested by Jean-Christophe PLAGNIOL-VILLARD

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.
