e413554f9d eNET: Remove config.mk
By including <config.h> in the ld script, CONFIG_SYS_MONITOR_LEN (defined
in the boards config file) can be used in lieu of FLASH_SIZE (defined in
the board specific config.mk)

As this is the last remaining entry in the board specific config.mk, this
file can now be removed

e9bf8877da eNET: Fix undefined reference to `monitor_flash_len'
commit cfbe861506 removed the definition of
monitor_flash_len from the eNET which was not picked up due to extensive
use of the SRAM configuration target for testing

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.

c8d76eaf60 Rename TEXT_BASE: fix merge conflicts
Commit 14d0a02a "Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE" missed a
few places, especially for boards that were added inbetween. Fix the
remaining issues.

14d0a02a16 Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE
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.

f2ff75c0a2 x86: Use loops instead of memcpy/memset in board_init_f
Provides a small speed increase and prepares for fully relocatable image.
Downside is the TEXT_BASE, bss, load address etc must ALL be aligned on a
a 4-byte boundary which is not such a terrible restriction as everything
is already 4-byte aligned anyway
