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.

The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.
Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.

Start of support of
Texas Instruments Software Development Platform(SDP)
for OMAP3430 - SDP3430
Highlights of this platform are:
Flash Memory devices:
Sibley NOR, Micron 8bit NAND and OneNAND
Connectivity:
3 UARTs and expanded 4 UART ports + IrDA
Ethernet, USB
Other peripherals:
TWL5030 PMIC+Audio+Keypad
VGA display
Expansion ports:
Memory devices plugin boards (PISMO)
Connectivity board for GPS,WLAN etc.
Completely configurable boot sequence and device mapping
etc.
Support default jumpering and:
- UART1/ttyS0 console(legacy sdp3430 u-boot)
- UART3/ttyS2 console (matching other boards,
and SDP HW docs)
- Ethernet
- mmc0
- NOR boot
Currently the UART1 is enabled by default. for
compatibility with other OMAP3 u-boot platforms,
enable the #define of CONSOLE_J9.
Conflicts:
Makefile
Fixed the conflict with smdkc100_config by moving omap_sdp3430_config
to it is alphabetically sorted location above zoom1.
