2013-04-12arm: Make all linker scripts compatible with per-symbol sectionsBenoît Thébaudeau
Let all ARM linker scripts handle properly -ffunction-sections and -fdata-sections. This will be useful for future changes in order to create symbol-specific sections in common .S files. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com>
2013-04-12arm: relocate_code(): Use __image_copy_end for end of relocationBenoît Thébaudeau
Use __image_copy_end instead of __bss_start for the end of the image to relocate. This is the same as commit 033ca72, but applied to all ARM start.S. This is a more appropriate symbol naming for an image copy & relocate feature, and this also saves a useless copy of data put between __image_copy_end and __bss_start in linker scripts (e.g. relocation information, or MMU initialization tables used only before jumping to the relocated image).

2013-03-18Merge branch 'master' of git://git.denx.de/u-boot-armTom Rini
Albert's rework of the linker scripts conflicted with Simon's making everyone use __bss_end. We also had a minor conflict over README.scrapyard being added to in mainline and enhanced in u-boot-arm/master with proper formatting. Conflicts: arch/arm/cpu/ixp/u-boot.lds arch/arm/cpu/u-boot.lds arch/arm/lib/Makefile board/actux1/u-boot.lds board/actux2/u-boot.lds board/actux3/u-boot.lds board/dvlhost/u-boot.lds board/freescale/mx31ads/u-boot.lds doc/README.scrapyard include/configs/tegra-common.h Build tested for all of ARM and run-time tested on am335x_evm.

2013-03-15Replace __bss_end__ with __bss_endSimon Glass
Note this is a tree-wide change affecting multiple architectures. At present we use __bss_start, but mostly __bss_end__. This seems inconsistent and in a number of places __bss_end is used instead. Change to use __bss_end for the BSS end symbol throughout U-Boot. This makes it possible to use the asm-generic/sections.h file on all archs. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-12Remove linker lists (LGAs) from SPL linker scriptsAlbert ARIBAUD
Many SPL linker scripts needlessly include linker lists (aka LGAs). Remove them whenever possible; keep it only in the seven am335x_evm variants (am335x_evm, am335x_evm_uart[1-5], am335x_evm_spiboot), where there is actual content in output section .u_boot_list. This commit keeps all u-boot.bin and u-boot-spl.bin in ARM targets byte-identical. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>
2012-10-22common: Add .u_boot_list into all linker filesMarek Vasut
Add section for the linker-generated lists into all possible linker files, so that everyone can easily use these lists. This is mostly a mechanical adjustment. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Joe Hershberger <joe.hershberger@gmail.com> Cc: Mike Frysinger <vapier@gentoo.org>
2012-10-15serial: pxa: Make use of default_serial_console in serial_pxaMarek Vasut
Make use of the newly implemented weak default_serial_console in the serial_pxa driver. This removes all reimplementations of this function from board files. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Marek Vasut <marek.vasut@gmail.com> Cc: Tom Rini <trini@ti.com>

2011-10-15punt unused clean/distclean targetsMike Frysinger
The top level Makefile does not do any recursion into subdirs when cleaning, so these clean/distclean targets in random arch/board dirs never get used. Punt them all. MAKEALL didn't report any errors related to this that I could see. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
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>

2010-10-18Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk
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.
