Add support for a saving build objects in a separate directory. Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.

ARM: compiler options cleanup - improve tool chain support For some time there have been repeated reports about build problems with some ARM (cross) tool chains. Especially issues about (in)compatibility with the tool chain provided runtime support library libgcc.a caused to add and support a private implementation of such runtime support code in U-Boot. A closer look at the code indicated that some of these issues are actually home-made. This patch attempts to clean up some of the most obvious problems and make building of U-Boot with different tool chains easier: - Even though all ARM systems basicy used the same compiler options to select a specific ABI from the tool chain, the code for this was distributed over all cpu/*/config.mk files. We move this one level up into lib_arm/config.mk instead. - So far, we only checked if "-mapcs-32" was supported by the tool chain; if yes, this was used, if not, "-mabi=apcs-gnu" was selected, no matter if the tool chain actually understood this option. There was no support for EABI conformant tool chains. This patch implements the following logic: 1) If the tool chain supports "-mabi=aapcs-linux -mno-thumb-interwork" we use these options (EABI conformant tool chain). 2) Otherwise, we check first if "-mapcs-32" is supported, and then check for "-mabi=apcs-gnu" If one test succeeds, we use the first found option. 3) In case 2), we also test if "-mno-thumb-interwork", and use this if the test succeeds. [For "-mabi=aapcs-linux" we set "-mno-thumb-interwork" mandatorily.] This way we use a similar logic for the compile options as the Linux kernel does. - Some EABI conformant tool chains cause external references to utility functions like raise(); such functions are provided in the new file lib_arm/eabi_compat.c Note that lib_arm/config.mk gets parsed several times, so we must make sure to add eabi_compat.o only once to the linker list.

Conditionally add -fno-stack-protector to CFLAGS When compile-testing on powerpc, I get errors like this: net/nfs.c:422: undefined reference to `__stack_chk_fail_local' This seems to be because -fstack-protector is on by default, so let's explicitly disable it on all architectures that support the option. The Ubuntu toolchain is affected by this problem, and according to Mike Frysinger, Gentoo has been running with SSP enabled for years. More and more distros are turning SSP on by default, so this problem is likely to get worse in the future. Also, powerpc just happens to be one of the arches I do compile-testing on. There may be other arches affected by this too. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

Fix all linker scripts for older binutils versions (pre-2.16) Commit f62fb99941c6 fixed handling of all rodata sections by using a wildcard combined with calls to ld's builtin functions SORT_BY_ALIGNMENT() and SORT_BY_NAME(). Unfortunately these functions were only introduced with biunutils version 2.16, so the modification broke building with all tool chains using older binutils. This patch makes it work again. This is done by omitting the use of these functions for such old tool chains. This will result in slightly larger target binaries, as the rodata sections are no longer in optimal order alignment-wise which reauls in unused gaps, but the effect was found to be insignificant - especially compared to the fact that you cannot build U-Boot at all in the current state. As ld seems to have no support for conditionals we run the linker script through the C preprocessor which can be easily used to remove the unwanted function calls. Note that the C preprocessor must be run with the "-ansi" (or a "-std=") option to make sure all the system-specific predefined macros outside the reserved namespace are suppressed. Otherise, cpp might for example substitute "powerpc" to "1", thus corrupting for example "OUTPUT_ARCH(powerpc)" etc. Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: Mike Frysinger <vapier@gentoo.org>

# Location of a usable BFD library, where we define "usable" as
# "built for ${HOST}, supports ${TARGET}". Sensible values are
# - When cross-compiling: the root of the cross-environment
# - Linux/ppc (native): /usr
# - NetBSD/ppc (native): you lose ... (must extract these from the
# binutils build directory, plus the native and U-Boot include
# files don't like each other)

# So far, this is used only by tools/gdb/Makefile.
build system: treat all Darwin's alike The x86 based version of Darwin behaves the same quirky way as the powerpc Darwin, so only check HOSTOS when setting up Darwin workarounds. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

allow boards to customize compiler options on a per-file/dir basis With our Blackfin boards, we like to build the compression routines with -O2 as our tests show a pretty good size/speed tradeoff. For the rest of U-Boot though, we want to stick with the default -Os as that is mostly control code. So in our case, we would add a line like so to the board specific config.mk file: CFLAGS_lib_generic += -O2 Now all files under lib_generic/ will have -O2 appended to their build.

# Allow boards to use custom optimize flags on a per dir/file basis
BCURDIR := $(notdir $(CURDIR))
Add support for a saving build objects in a separate directory. Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.

add %.c->%.i and %.c->%.s rules The Linux kernel has some helper rules which allow you to quickly produce some of the intermediary files from C source. Specifically, you can create .i files which is the preprocessed output and you can create .s files which is the assembler output. This is useful when you are trying to track down header/macro expansion errors or inline assembly errors.
