* ColdFire: Cleanup for partial linking and --gc-sectionsJason Jin2011-09-04-125/+24
| | | | | | | | Introduce the --gc-sections for ColdFire platform and clean up the corresponding lds file. Signed-off-by: TsiChung Liew <tsicliew@gmail.com> Signed-off-by: Jason Jin <Jason.jin@freescale.com>
* rename _end to __bss_end__Po-Yu Chuang2011-03-27-2/+2
| | | | | | | Currently, _end is used for end of BSS section. We want _end to mean end of u-boot image, so we rename _end to __bss_end__ first. Signed-off-by: Po-Yu Chuang <ratbert@faraday-tech.com>
* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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_BASEWolfgang Denk2010-10-18-1/+1
| | | | | | | | | | | | 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.

* Rename lib_generic/ to lib/Peter Tyser2010-04-13-2/+2
| | | | | | | | Now that the other architecture-specific lib directories have been moved out of the top-level directory there's not much reason to have the '_generic' suffix on the common lib directory. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* Move lib_$ARCH directories to arch/$ARCH/libPeter Tyser2010-04-13-2/+2
| | | | | | | | | Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk This change is intended to clean up the top-level directory structure and more closely mimic Linux's directory organization. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

* ColdFire: Remove platforms mii.c fileTsiChung Liew2008-11-03-304/+1
| | | | | | | | | | | Will use mcfmii.c driver in drivers/net rather than keep creating new mii.c for each future platform. Remove EB+MCF-EV123, cobra5272, idmr, M5235EVB, M5271EVB, M5272C3, M5275EVB, M5282EVB, M5329EVB, M5373EVB, M54451EVB, M54455EVB, M547xEVB, and M548xEVB's mii.c Signed-off-by: TsiChung Liew <Tsi-Chung.Liew@freescale.com>
