* POWERPC: enable --gc-sections and -ffunction-sections -fdata-sectionsWolfgang Denk2010-11-27-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | | The switch from archive libraries to partial linking has introduced a number of problems, that are non-trivial to solve. For example, it is no longer possible to include individual object files in the linker script as we did before for example in the case of boards with embedded environment to fill up the gap caused by the need to align the environment on flash erase block boundaries. The best (but unfortunately not easiest) approach to address this problem is to enable -ffunction-sections (and -fdata-sections) so we can again (and even in much finer granularity) place certain code where we want it. When doing this step, it seems only consequent to also add --gc-sections which has the added benefit of reducing the memory footprint of the U-Boot image (both in flash and in RAM). Unfortunately, this requires changes to a lot of linker scripts.

* arch/powerpc/*/config.mk: make CONFIG_SYS_LDSCRIPT settings workWolfgang Denk2010-11-26-50/+20
| | | | | | | | | | | | | | | | | | | | | | | | | As we try to get rid of board specific config.mk files we must provide a way for board specific settings of the LDSCRIPT variable (path to the linker script) where needed. We now implement the following hierarchy: - Highest priority has a "#define CONFIG_SYS_LDCONFIG" in the board config file. - If CONFIG_SYS_LDCONFIG is not set, and the system is booting from NAND (CONFIG_NAND_SPL is set), then a board specific linker script board/$(BOARDDIR)/u-boot-nand.lds gets used. - If we are not booting from NAND, we test if a processor specific linker script arch/powerpc/cpu/$(CPU)/u-boot.lds exists; if so we use that. - As default, arch/powerpc/config.mk gets used.

* WINBOND_83C553: enable only on boards that actually use it.Wolfgang Denk2010-11-26-1/+1
| | | | | | | | | | | | | | | | | | | | So far, only the BAB7xx board would call the initialise_w83c553f() function for the WINBOND 83C553 chip, even though some other boards (HIDDEN_DRAGON, Sandpoint8240, Sandpoint8245) enabled it in their board configuration. These boards were also missing other config settings needed for that, which resulted in build errors like this: drivers/pci/libpci.o:(.got2+0x84): undefined reference to `ide_bus_offset' Switch arch/powerpc/lib/board.c to call initialise_w83c553f() not on a per-board base, but when a WINBOND_83C553 in enabled in a configuration (like BAB7xx), and disable it in the boards that had this set so far.

* | Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-181/+181
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
