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.

This change does the following:
- Removes the printing of the PCI interrupt line value. This is
normally set to 0 by U-Boot on bootup and is rarely used during
everyday operation.
- Prints out the PCI function number of a device. Previously a device
with multiple functions would be printed identically 2 times, which is
generally confusing. For example, on an Intel 2 port gigabit Ethernet
card the following was displayed:
...
04 01 8086 1010 0200 00
04 01 8086 1010 0200 00
...
- Prints a text description of each device's PCI class instead of the
raw PCI class code. The textual description makes it much easier to
determine what devices are installed on a PCI bus.
- Changes the general formatting of the PCI device output.

Function omap3_evm_get_revision() - to identify the
board revision was called at end of setup_net_chip().
Board revision can be ascertained only by identifying
the Ethernet chipset - but combining setup operations
with revision detection isn't a good idea. So, moved
the function after call to setup_net_chip().
Function setup_net_chip() should be ideally be called
only when CONFIG_CMD_NET is defined. But this leaves
the board revision "undetected". This patch allows
static definition of revision or default fallback to

For ARM systems, before ELF relocation was introduced,
CONFIG_SKIP_RELOCATE_UBOOT coul be used to prevent *COPYING* the
U-Boot image from whereever it was loaded to it's link address
(CONFIG_SYS_TEXT_BASE). The name was badly chosen, as no relocation
was performed at all, it was just a memcpy().
With ELF relocation, this does not work like that any more, and
related boards need to be fixed anyway. So don't keep this relict any
longer.

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.

This patch is to fix build breakage and support new relocation
scheme for mx51evk.
- Correct IRAM base address and add size definition
The IRAM starts from 0x1FFE0000 on final revsion i.mx51 than
0x1FFE8000 which is for older revision.
- Include imx-regs.h in mx51evk.h
Definitions like CSD0_BASE_ADDR and IRAM_BASE_ADDR can be
referred to.
- Define CONFIG_SYS_INIT_RAM_ADDR and CONFIG_SYS_INIT_RAM_SIZE
They are used to define init RAM layout.

The mx51evk u-boot has an issue that system will get reset
every 2 hours.
MC13892 has an inside charge timer which expires in 120 minutes.
If ICHRG and CHGAUTOB are not set properly, this timer expiration
will get system power recycled.
Since mx51evk has no Li-Ion battery on board, the patch sets
ICHRG in externally powered mode and sets CHGAUTOB bit to avoid
automatic charging, so that system will not get reset by this
timer expiration.
The patch also corrects the bit field definition of register 48
(Charger 0) per latest MC13892 Reference Manual.

CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool. In the result, all definitions of this value can be
deleted from the board config files. We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.
No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

A recurrent issue is that certain C level constructs like sizeof() or
offsetof() cannot be used in assembler files, which is inconvenient
when such constructs are used in the definition of macro names etc.
To avoid duplication of such definitions (and thus another cause of
problems), we adapt the Linux way to automatically generate the
respective definitions from the respective C header files.
In Linux, this is implemented in include/linux/kbuild.h, Kbuild, and
arch/*/kernel/asm-offsets.c; we adapt the code from the Linux v2.6.36
kernel tree.
We also copy the concept of the include/generated/ directory which can
be used to hold other automatically generated files as well.
We start with an architecture-independent lib/asm-offsets.c which
generates include/generated/generic-asm-offsets.h (included by
include/asm-offsets.h, which is what will be referred to in the actual
source code). Later this may be extended by architecture-specific
arch/*/lib/asm-offsets.c files that will generate a
include/generated/asm-offsets.h.

family. For example, the XPedite5370, XPedite5371, and XPedite5372 are
similar enough that one U-Boot image can work on all 3 cards. To make it
