Add flags to tell objcopy what kind of ELF to create. Signed-off-by: Samuel Holland <samuel@sholland.org>
2023-04-20riscv: Enforce DWARF4 outputBin Meng1-2/+1
Since commit 409e4b547872 ("Makefile: Enforce DWARF4 output") the whole U-Boot build switched to enforce DWARF4 output, but RISC-V is still on its own setting. Let's switch to use U-Boot's setting. Signed-off-by: Bin Meng <bmeng@tinylab.org> Reviewed-by: Leo Yu-Chi Liang <ycliang@andestech.com>

2020-04-10kconfig / kbuild: Re-sync with Linux 4.19Tom Rini1-2/+2
Align Kconfig and Kbuild logic to Linux 4.19 release with minimal impact on files outside of this scope. Our previous Kconfig sync was done by commit 5972ff077e0f ("kconfig / kbuild: re-sync with Linux 4.18"). In this particular re-sync in order to keep clang support working a number of related changes needed to be pulled in that had been missed previously. Not all of these changes we easily traceable and so have been omitted from the list below. The imported Linux commits are: [From prior to v4.18] 9f3f1fd29976 kbuild: Add __cc-option macro d7f14c66c273 kbuild: Enable Large File Support for hostprogs 6d79a7b424a5 kbuild: suppress warnings from 'getconf LFS_*' 24403874316a Shared library support 86a9df597cdd kbuild: fix linker feature test macros when cross compiling with Clang 0294e6f4a000 kbuild: simplify ld-option implementation [From v4.18 to v4.19] 96f14fe738b6 kbuild: Rename HOSTCFLAGS to KBUILD_HOSTCFLAGS 10844aebf448 kbuild: Rename HOSTCXXFLAGS to KBUILD_HOSTCXXFLAGS b90a368000ab kbuild: Rename HOSTLDFLAGS to KBUILD_HOSTLDFLAGS 8377bd2b9ee1 kbuild: Rename HOST_LOADLIBES to KBUILD_HOSTLDLIBS f92d19e0ef9b kbuild: Use HOST*FLAGS options from the command line 4ab3b80159d4 kconfig: check for pkg-config on make {menu,n,g,x}config 693359f7ac90 kconfig: rename SYMBOL_AUTO to SYMBOL_NO_WRITE f60b992e30ff kbuild: replace $(LDFLAGS) $(ldflags-y) with $(ld_flags) 2fb9279f2c3e kbuild: change ld_flags to contain LDFLAGS_$(@F) c931d34ea085 arm64: build with baremetal linker target instead of Linux when available 5accd7f3360e kconfig: handle format string before calling conf_message_callback() a2ff4040151a kconfig: rename file_write_dep and move it to confdata.c 0608182ad542 kconfig: split out useful helpers in confdata.c adc18acf42a1 kconfig: remove unneeded directory generation from local*config 79123b1389cc kconfig: create directories needed for syncconfig by itself 16952b77d8b5 kconfig: make syncconfig update .config regardless of sym_change_count d6c6ab93e17f kbuild: remove deprecated host-progs variable 56869d45e364 kconfig: fix the rule of mainmenu_stmt symbol c151272d1687 kconfig: remove unused sym_get_env_prop() function 1880861226c1 kconfig: remove P_ENV property type e3fd9b5384f3 scripts/dtc: consolidate include path options in Makefile 4bf6a9af0e91 kconfig: add build-only configurator targets f1575595d156 kconfig: error out when seeing recursive dependency 5e8c5299d315 kconfig: report recursive dependency involving 'imply' f498926c47aa kconfig: improve the recursive dependency report 98a4afbfafd2 kconfig: fix "Can't open ..." in parallel build 9a9ddcf47831 kconfig: suppress "configuration written to .config" for syncconfig 87a32e624037 kbuild: pass LDFLAGS to recordmcount.pl d503ac531a52 kbuild: rename LDFLAGS to KBUILD_LDFLAGS 217c3e019675 disable stringop truncation warnings for now bc8d2e20a3eb kconfig: remove a spurious self-assignment fd65465b7016 kconfig: do not require pkg-config on make {menu,n}config 5a4630aadb9a ftrace: Build with CPPFLAGS to get -Qunused-arguments Note that this adds new cleanup work to do in that we should adapt the shared library support we have to what is now upstream.

2019-01-15riscv: qemu: define standalone load addressLukas Auer1-1/+1
We need to define the standalone load address to use standalone application on qemu-riscv. Define it and set it equal to CONFIG_SYS_LOAD_ADDR. To not overwrite it, change the assigned of CONFIG_STANDALONE_LOAD_ADDR in arch/riscv/config.mk to a conditional one.

2019-01-15riscv: remove RISC-V standalone linker scriptLukas Auer1-1/+0
Standalone applications do not require a separate linker script and can use the default linker script of the compiler instead. Remove the RISC-V standalone linker script.

2018-11-26riscv: set -march and -mabi based on the Kconfig configurationLukas Auer1-4/+0
Use the new Kconfig entries to construct the ISA string for the -march compiler flag. The -mabi compiler flag is selected based on the base integer instruction set. With this change, the C (compressed instructions) ISA extension is now enabled for all boards with CONFIG_RISCV_ISA_C set. Buildman reports a decrease in binary size of 71590 bytes.

2018-10-03riscv: allow native compilationHeinrich Schuchardt1-4/+0
If environment variable CROSS_COMPILE is not set, this indicates native compilation. In this case we should not set an arbitrary value which is not applicable for 64bit anyway. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2018-10-03riscv: Explicitly pass -march and -mabi to the compilerBin Meng1-2/+6
At present the compiler flag against which architecture and abi variant the riscv image is built for is not explicitly indicated which means the default compiler configuration is used. But this does not work if we want to build a different target (eg: 32-bit riscv images using a toolchain configured for 64-bit riscv). Fix this by explicitly passing -march and -mabi to the compiler. Since generically we don't use floating point in U-Boot, specify the RV[32|64]IMA ISA and software floating ABI. This also fix some alignment coding style issues.

2018-05-29riscv: Enable function sectionsAlexander Graf1-1/+1
The linker can remove sections that are never addressed, so it makes a lot of sense to declare every function as an individual section. This reduces the output U-Boot code size by ~30kb for me. Signed-off-by: Alexander Graf <agraf@suse.de>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-1/+1
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
