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.

d48abea4b8 Add proper copyright notices in Atmel boards Makefiles
The Makefiles for the AT91CAP9/AT91SAM9 boards have an incomplete
copyright notice. This patch adds the missing pieces.

567fb85217 Fix @ -> <at> substitution
When applying the AT91CAP9 patches upstream, something transformed
the '@' character into the ' <at> ' sequence.

The patch below restores the original form in all the places where
it has been modified (the AT91CAP9 files, the AT91SAM9260 files which
were copied from AT91CAP9, and a couple of other files where the
' <at> ' sequence was present).

c3a60cb3bd Clean up dataflash partitioning
This patch removes the board dependent parts from
"drivers/mtd/dataflash.c".
Each board relying on this, will have the appropriate
code in a new file, "partition.c" in the board directory.
board Makefiles updated to use the file.

The dataflash partitions are aligned on sector/page boundaries.

The CONFIG_NEW_DF_PARTITION was used to create named partitions
This is now the default operation, and the CONFIG variable is removed.
