2010-11-17Switch from archive libraries to partial linkingSebastien Carlier
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>
2010-04-08ati_radeon: Support PCI virtual not eq bus mapping.Ed Swarthout
Use pci_bus_to_virt() to convert the bus address from the BARs to virtual address' to eliminate the direct mapping requirement. Rename variables to better match usage (_phys -> _bus or no-suffix) This fixes the mpc8572ds CONFIG_PHYS_64BIT mode failure: "videoboot: Video ROM failed to map!" Tested on mpc8572ds with and without CONFIG_PHYS_64BIT. Signed-off-by: Ed Swarthout <Ed.Swarthout@freescale.com>

2009-10-12Leave x86emu op code tables in default sectionEd Swarthout
Forcing the tables into got2 caused extra relocation when using -mrelocatable. This patch requires any board defining CONFIG_BIOSEMU to use -mrelocatable. Signed-off-by: Ed Swarthout <Ed.Swarthout@freescale.com> Acked-by: Jin Zhengxiong <Jason.Jin@freescale.com>

2008-05-21Big white-space cleanup.Wolfgang Denk
This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>
