2017-06-16powerpc, 5xxx, 512x: remove support for mpc5xxx and mpc512xHeiko Schocher
There was for long time no activity in the mpx5xxx area. We need to go further and convert to Kconfig, but it turned out, nobody is interested anymore in mpc5xxx, so remove it. Signed-off-by: Heiko Schocher <hs@denx.de>

There was for long time no activity in the 8xx area. We need to go further and convert to Kconfig, but it turned out, nobody is interested anymore in 8xx, so remove it (with a heavy heart, knowing that I remove here the root of U-Boot). Signed-off-by: Heiko Schocher <hs@denx.de>
2015-11-10arm: support Thumb-1 with CONFIG_SYS_THUMB_BUILDAlbert ARIBAUD
When building a Thumb-1-only target with CONFIG_SYS_THUMB_BUILD, some files fail to build, most of the time because they include mcr instructions, which only exist for Thumb-2. This patch introduces a Kconfig option CONFIG_THUMB2 and uses it to select between Thumb-2 and ARM mode for the aforementioned files. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

2014-05-23examples: select libgcc for non-default architectureAlexey Brodkin
In case of multilib-enabled toolchains if default architecture differ from the one examples are being built for linker will fail to link example object files with libgcc of another (non-compatible) architecture. Interesting enough for years in main Makefile we used CFLAGS/c_flags for this but not for examples. So fixing it now.

2014-03-07powerpc: mpc8260: consolidate CONFIG_MPC8260 and CONFIG_8260Masahiro Yamada
Before this commit, CONFIG_MPC8260 and CONFIG_8260 were used mixed-up. All boards with mpc8260 cpu defined both of them: - CONFIG_MPC8260 was defined in board config headers and include/common.h - CONFIG_8260 was defined arch/powerpc/cpu/mpc8260/config.mk We do not need to have both of them. This commit keeps only CONFIG_MPC8260. This commit does: - Delete CONFIG_8260 and CONFIG_MPC8260 definition in config headers and include/common.h - Rename CONFIG_8260 to CONFIG_MPC8260 in arch/powerpc/cpu/mpc8260/config.mk. - Rename #ifdef CONFIG_8260 to #ifdef CONFIG_MPC8260 Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Cc: Wolfgang Denk <wd@denx.de>
2014-03-07kbuild: improve Kbuild speedMasahiro Yamada
Kbuild brought about many advantages for us but a significant performance regression was reported by Simon Glass. After some discussions and analysis, it turned out its main cause is in $(call cc-option,...). Historically, U-Boot parses all config.mk (arch/*/config.mk and board/*/config.mk) every time descending into subdirectories. That means cc-options are evaluated over and over again. $(call cc-option,...) is useful but costly. So we want to evaluate them only in ./Makefile and spl/Makefile and export compiler flags. This commit changes the build system as follows: - Modify scripts/Makefile.build to not include config.mk Instead, add $(PLATFORM_CPPFLAGS) to asflags-y, ccflags-y, cppflags-y. - Export many variables Going forward, Kbuild will not parse config.mk files when it descends into subdirectories. If we want to set variables in config.mk and use them in subdirectories, they must be exported. This is the list of variables to get exported: PLATFORM_CPPFLAGS CPUDIR BOARDDIR OBJCOPYFLAGS LDFLAGS LDFLAGS_FINAL (used in nand_spl/board/*/*/Makefile) CONFIG_STANDALONE_LOAD_ADDR (used in examples/standalone/Makefile) SYM_PREFIX (used in examples/standalone/Makefile) RELFLAGS (used in examples/standalone/Makefile) - Delete CPPFLAGS This variable has been replaced with PLATFORM_CPPFLAGS - Copy gcclibdir from example/standalone/Makefile to arch/sparc/config.mk The reference in CONFIG_STANDALONE_LOAD_ADDR must be resolved before it is exported.

2014-02-19kbuild: use Linux Kernel build scriptsMasahiro Yamada
Now we are ready to switch over to real Kbuild. This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.

2014-02-19kbuild: change out-of-tree buildMasahiro Yamada
This commit changes the working directory where the build process occurs. Before this commit, build process occurred under the source tree for both in-tree and out-of-tree build. That's why we needed to add $(obj) prefix to all generated files in makefiles like follows: $(obj)u-boot.bin: $(obj)u-boot Here, $(obj) is empty for in-tree build, whereas it points to the output directory for out-of-tree build. And our old build system changes the current working directory with "make -C <sub-dir>" syntax when descending into the sub-directories. On the other hand, Kbuild uses a different idea to handle out-of-tree build and directory descending. The build process of Kbuild always occurs under the output tree. When "O=dir/to/store/output/files" is given, the build system changes the current working directory to that directory and restarts the make. Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>" syntax for descending into sub-directories. (We can write it like "make $(obj)=<sub-dir>" with a shorthand.) This means the current working directory is always the top of the output directory. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Tested-by: Gerhard Sittig <gsi@denx.de>

2013-09-12Revert "standalone-examples: support custom GCC lib"Tom Rini
After further testing, this patch has two problems. First, examples/standalone/Makefile was already inherting PLATFORM_LIBS from the top-level Makefile so this lead to duplicating the private libgcc. Second, currently the private libgcc has a reference to 'hang' that is not being fulfilled. This reverts commit 4412db46468d5965da736d06f84d13e68a6e0b51. Signed-off-by: Tom Rini <trini@ti.com>

2011-11-03Reduce build timesWolfgang Denk
U-Boot Makefiles contain a number of tests for compiler features etc. which so far are executed again and again. On some architectures (especially ARM) this results in a large number of calls to gcc. This patch makes sure to run such tests only once, thus largely reducing the number of "execve" system calls. Example: number of "execve" system calls for building the "P2020DS" (Power Architecture) and "qong" (ARM) boards, measured as: -> strace -f -e trace=execve -o /tmp/foo ./MAKEALL <board> -> grep execve /tmp/foo | wc -l Before: After: Reduction: ================================== P2020DS 20555 15205 -26% qong 31692 14490 -54% As a result, built times are significantly reduced, typically by 30...50%.

2011-05-12Fix variable flavor in examples/standalone/MakefileChe-liang Chiou
GNU Makefile have two flavors of variables, recursively expanded that is defined by using '=', and simply expanded that is defined by using ':='. The bug is caused by using recursively expanded flavor for BIN and SREC. As you can see below, they are prepended by $(obj) twice. We can reproduce this bug with a simplified version of this Makefile: $ cat >Makefile <<\EOF obj := /path/to/obj/ ELF := hello_world BIN_rec = $(addsuffix .bin,$(ELF)) # recursively expanded BIN_sim := $(addsuffix .bin,$(ELF)) # simply expanded ELF := $(addprefix $(obj),$(ELF)) BIN_rec := $(addprefix $(obj),$(BIN_rec)) BIN_sim := $(addprefix $(obj),$(BIN_sim)) show: @echo BIN_rec=$(BIN_rec) @echo BIN_sim=$(BIN_sim) .PHONY: show EOF $ make show BIN_rec=/path/to/obj//path/to/obj/hello_world.bin BIN_sim=/path/to/obj/hello_world.bin Signed-off-by: Che-Liang Chiou <clchiou@chromium.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>
2010-10-12examples/standalone: Use gcc's -fno-toplevel-reorderPeter Tyser
Using -fno-toplevel-reorder causes gcc to not reorder functions. This ensures that an application's entry point will be the first function in the application's source file. This change, along with commit 620bbba524fbaa26971a5004793010b169824f1b should cause a standalone application's entry point to be at the base of the compiled binary. Previously, the entry point could change depending on gcc version and flags. Note -fno-toplevel-reorder is only available in gcc version 4.2 or greater.

2010-06-29examples/standalone: Remove relocation compile flags for PowerPCPeter Tyser
Previously, standalone applications were compiled with gcc flags that produced relocatable executables on the PowerPC architecture (eg with the -mrelocatable and -fPIC flags). There's no reason for these applications to be fully relocatable at this time since no relocation fixups are performed on standalone applications. Additionally, removing the gcc relocation flags results in the entry point of applications residing at the base of the image. When a standalone application was relocatable, the entry point was generally located at an offset into the image which was confusing and prone to errors. This change moves the entry point of PowerPC standalone applications from 0x40004 (usually) to 0x40000. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Wolfgang Denk <wd@denx.de>
2009-12-02Fix build failure in examples/standaloneSanjeev Premi
Some versions of 'make' do not handle trailing white-spaces properly. Trailing spaces in ELF causes a 'fake' source to be added to the variable COBJS; leading to build failure (listed below).

2009-09-04atmel_df_pow2: standalone to convert dataflashes to pow2Mike Frysinger
Atmel DataFlashes by default operate with pages that are slightly bigger than normal binary sizes (i.e. many are 1056 byte pages rather than 1024 bytes). However, they also have a "power of 2" mode where the pages show up with the normal binary size. The latter mode is required in order to boot with a Blackfin processor, so many people wish to convert their DataFlashes on their development systems to this mode. This standalone application does just that. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-08-08Fix examples for OMAP3 boards...Michael Evans
The attached patch corrects an error in the examples/Makefile which causes the applications in the examples directory to hang on OMAP3 based boards. The current Makefile sets -Ttext during linking to 0x0c100000 which is outside of addressable SDRAM memory. The script corrects the existing ifeq...else...endif logic to look at the VENDOR tag rather than the CPU tag.
