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.

Split the display command into generic interface and hardware-specific
realization for PDSP188x LED display found on hmi1001 and manroland
boards. Simple interface for LED displays is defined in
include/led-display.h and described in doc/README.LED_display.
Driver-specific implementation was moved into drivers/misc/pdsp188x.c
file (enabled with CONFIG_PDSP188x set).

This patch adds a status led driver followed the GPIO access
conventions of Linux. The led mask is used to specify the gpio pin.

The patch add supports for the Freescale's Power
Management Controller (known as Atlas) used together with i.MX31/51
processors. It was tested with a MC13783 (MX31) and
MC13892 (MX51).

Because twl4030 now has its own device files, move exiting
omap3 power_init_r to a new location.
power_init_r is the only function in board/omap3/common.
It initializes the twl4030 power for the board and enables
the led.
The power part of the the function is moved to twl4030_power_init in
drivers/power/twl4030.c The power compilation is conditional on the
existing config variable CONFIG_TWL4030_POWER.
The led part is moved to twl4030_led_init in the new file
drivers/misc/twl4030_led.c The led compilation is conditional on
the new config variable CONFIG_TWL4030_LED
The directory board/omap3/common was removed because power_init_r
was the only function in it.

Initial support for the DS4510, a CPU supervisor with
integrated EEPROM, SRAM, and 4 programmable non-volatile
GPIO pins. The CONFIG_DS4510 define enables support
for the device while the CONFIG_CMD_DS4510 define
enables the ds4510 command. The additional
CONFIG_DS4510_INFO, CONFIG_DS4510_MEM, and
CONFIG_DS4510_RST defines add additional sub-commands
to the ds4510 command when defined.

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.

Move the initialization of the LAWs into C code and provide an API
to allow modification of LAWs after init.
Board code is responsible to provide a law_table and num_law_entries.
We should be able to use the same code on 86xx as well.
