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>

2009-08-26ColdFire: Fix compile warning messagesTsiChung Liew
Change %08lX to %08X in board.c. Remove unused variable 'oscillator' in mcf5227x/cpu_init.c and 'scm2' in mcf532x/cpu_init.c. Provide argument type cast in drivers/dma/MCD_dmaApi.c. Signed-off-by: TsiChung Liew <tsicliew@gmail.com>

2009-07-01fsl_dma: Make DMA transactions snoopablePeter Tyser
Make DMA transactions snoopable so that CPUs can keep caches up-to-date. This allows dma transactions to be used for operations such as memory copies without any additional cache control operations.

2009-07-018xxx: Rename dma_xfer() to dmacpy()Peter Tyser
Also update dmacpy()'s argument order to match memcpy's and use phys_addr_t/phy_size_t for address/size arguments Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-07-01fsl_dma: Fix Channel Start bug in dma_check()Peter Tyser
The Channel Start (CS) bit in the Mode Register (MR) should actually be cleared as the comment in the code suggests. Previously, CS was being set, not cleared. Assuming normal operation of the DMA engine, this change shouldn't have any real affect. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

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>
