Switch from archive libraries to partial linking 2010-11-17T20:02:18+00:00 Sebastien Carlier sebastien.carlier@gmail.com 2010-11-05T14:48:07+00:00 6d8962e814c15807dd6ac5757904be2a02d187b8 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. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>

Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE 2010-10-18T20:07:10+00:00 Wolfgang Denk wd@denx.de 2010-10-07T19:51:12+00:00 14d0a02a168b36e87665b8d7f42fa3e88263d26d 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.
