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.

arm: include: Import unified.h from Linux kernel Import unified.h from Linux kernel 4.4.6 , commit 0d1912303e54ed1b2a371be0bba51c384dd57326 . This header file contains macros used in libgcc functions in Linux kernel on ARM and will be needed for the libgcc sync. Since unified.h defines the W(instr) macro, we must drop this from the macro from memcpy.S , otherwise this triggers a warning about symbol redefinition. In order to keep the changes to unified.h to the minimum, tweak arch/arm/lib/Makefile such that it defines the CONFIG_ARM_ASM_UNIFIED macro, which places .syntax unified into all of the assembler files. This is mandatory. Moreover, for Thumb2 build, define CONFIG_THUMB2_KERNEL macro if and only if Thumb2 build is enabled. This macro is checked by unified.h and toggles between ARM and Thumb2 variant of the instructions in the assembler source files. Finally, this patch defines __LINUX_ARM_ARCH__=N macro based on the new CONFIG_SYS_ARM_ARCH Kconfig option. This macro selects between more optimal and more dense codepaths which work on armv5 and newer and less optimal codepaths which work on armv4 and possible armv3m. Tegra2 needs the same special handling as it does in arch/arm/Makefile to cater for the arm720t boot core.
