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.

After moving the definition of CONFIG_SYS_TEXT_BASE to the respective
board config files, all Marvell kirkwood board have just a single and
common entry in their config.mk files:
KWD_CONFIG = $(SRCTREE)/board/$(BOARDDIR)/kwbimage.cfg
Replace the only reference to KWD_CONFIG in the top level Makefile by
an equivalent setting, and remove all kirkwood config.mk files.

It has been observed that, the complete u-boot banner
does not appear on the console when the system is booted
from NAND/NOR/SPI flash.
This patch fixes this issue on all Marvell boards by adding
board_early_init_f() support

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.

For all Kirkwood boards so far dram_init function is duplicated
dram_init function is moved to dram.c and relevant code from all
board specific files removed
If any board needs specific dram init handling than standard one,
then, a macro CONFIG_SYS_BOARD_DRAM_INIT should be defined in
board config header file and the dram_init function can be put
in board specific source file
For ex. keymile boards

value
The SheevaPlug DevKit is shipped with 4x8 by 1Gb DDR devices in
two banks for a total of 512MB of RAM. Based on this configuration
the existing values for SDRAM address control register are incorrect
and result in random kernel oops as memory is incorrectly accessed
(while for example extracting a large tarball such as a rootfs).
Based on the hardware configuration along with the supporting
documentation from Marvell these are the correct values, as
well this change mimics values previously used in Marvell's own
u-boot git tree for the SheevaPlug.
Other variants of the hardware such as the PogoPlug and TonidoPlug
may have different memory configurations but to properly support
those additional board directories should be maintained or a better
system to support other kwb*.cfg is needed.
Tested on SheevaPlug DevKit.

This patch is tested for-
1. Boot from DRAM/NAND flash
2. File transfer using tftp
3. NAND flash read/write/erase
4. Linux kernel and RFS Boot from NAND
5. Enabled USB PHY init for kernel need
6. Boot from USB supported
Note: to boot Kirkwood kernel with USB support,
you should add "usb start" in the boot sequence
