b823fd9ba5 ARM: prevent misaligned array inits
Under option -munaligned-access, gcc can perform local char
or 16-bit array initializations using misaligned native
accesses which will throw a data abort exception. Fix files
where these array initializations were unneeded, and for
files known to contain such initializations, enforce gcc
option -mno-unaligned-access.

[trini: Switch to usign call cc-option for -mno-unaligned-access as
Albert had done previously as that's really correct]

491f6c2f29 edminiv2: orion5x: fix GPIO inits and values
Orion5x did not actually write GPIO output values
or input polarities, and ED Mini V2 had bad or

96f5c4b2c9 bugfix: all Marvell specific build fails due to undefined reference to `get_ticks'
after http://patchwork.ozlabs.org/patch/136415/ was applied. All Marvell
build fails with below error

common/libcommon.o: In function `cread_line':
/home/uboot/src/u-boot-arm/common/main.c:717: undefined reference to `get_ticks'

/home/uboot/src/u-boot-arm/common/main.c:720: undefined reference to `get_ticks'

The same is fixed for Kirkwood, ARMADA100, pantheon and orion5x SoCs

5ff8b35412 ARM: orion5x: reduce dependence of including platform file
For files like the drivers/serial/serial.c, it must include the
platform file, as the CONFIG_SYS_NS16550_COM1 must reference to
the definition in the platform definition files.

Include the platform definition file in the config file, so that it
would decouple the dependence for the driver files.

17659d7de9 Timer: Remove reset_timer_masked()
In some circumstances, reset_timer_masked() was called be timer_init() in
order to perform architecture specific timer initialisation. In such
cases, the required code in reset_timer_masked() has been moved into

c9ac3ba129 arm926ejs: timer: Replace bss variable by gdr
Reuse the gd->tbl value for timestamp and add gd->lastinc for lastinc bss
values in the arm926ejs timers implementation.

The usage of bss values in drivers before initialisation of bss is forbidden.
In that special case some data in .rel.dyn gets corrupted.

This patch is similiar to the patch Dirk Behme posted
for the armv7/omap-common/timer.c and added suggestions
from Reinhard Meyer.

Tested on the arm926ejs mx27 based magnesium board
Tested on the arm926ejs kirkwood based suen3 board

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

a9aa392629 Drop support for CONFIG_SYS_ARM_WITHOUT_RELOC
When this define was introduced, the idea was to provide a soft
migration path for ARM boards to get adapted to the new relocation
support.  However, other recent changes led to a different
implementation (ELF relocation), where this no longer works.  By now
CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it
actually hurts because it obfuscates the actual code by sprinkling it
with lots of dead and non-working debris.

So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC.

ab86f72c35 ARM: implement relocation for ARM926
Change the implementation for arm926 to relocate the code to
an arbitrary address in RAM.

Adapt the TX25 (i.MX25), magnesium board to test the changes.

On the tx25 board TEXT_BASE is set to the final relocation
address to prevent one more copying of u-boot code
when relocating. More info see:

Fix orion5x_winctrl_calcsize() off-by-1 bug which caused mapping
windows to be cut by half. This afected all windows including NOR
flash (causing half the flash to be unaccessible) but DRAM was and
still is fine as its size is determined otherwise.

Turn all ORION5X_DEF{ADR,SZ}_xxx macros into ORION5X_{ADR,SZ}_xxx
and allow defining them from board code to override defaults. This
is particularly useful for defining board-specific FLASH address

code.
