Make STANDALONE_LOAD_ADDR configurable per board Rename STANDALONE_LOAD_ADDR into CONFIG_STANDALONE_LOAD_ADDR and allow that the architecture-specific default value gets overwritten by defining the value in the board header file.

push LOAD_ADDR out to arch mk files Rather than maintain/extend the current ifeq($(ARCH)) mess that exists in the standalone Makefile, push the setting up of LOAD_ADDR out to the arch config.mk (and rename to STANDALONE_LOAD_ADDR in the process). This keeps the common code clean and lets the arch do whatever crazy crap it wants in its own area. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

x86: Enable 32-bit build using x86_64 multilib toolchain Until now building the x86 arch boards required 32-bit toolchain. As many x86_64 toolchains come with 32-bit support (multilib) that's a good idea to enable build with such toolchains. The change required was to specify the usage of 32-bit explicitly to the compiler and the linker (-m32 and -m elf_i386 flags) and locate the right libgcc path.

x86: Wrap small helper functions from libgcc to avoid an ABI mismatch When gcc compiles some 64 bit operations on a 32 bit machine, it generates calls to small functions instead of instructions which do the job directly. Those functions are defined in libgcc and transparently provide whatever functionality was necessary. Unfortunately, u-boot can be built with a non-standard ABI when libgcc isn't. More specifically, u-boot uses -mregparm. When the u-boot and libgcc are linked together, very confusing bugs can crop up, for instance seemingly normal integer division or modulus getting the wrong answer or even raising a spurious divide by zero exception. This change borrows (steals) a technique and some code from coreboot which solves this problem by creating wrappers which translate the calling convention when calling the functions in libgcc. Unfortunately that means that these instructions which had already been turned into functions have even more overhead, but more importantly it makes them work properly. To find all of the functions that needed wrapping, u-boot was compiled without linking in libgcc. All the symbols the linker complained were undefined were presumed to be the symbols that are needed from libgcc. These were a subset of the symbols covered by the coreboot code, so it was used unmodified. To prevent symbols which are provided by libgcc but not currently wrapped (or even known about) from being silently linked against by code generated by libgcc, a new copy of libgcc is created where all the symbols are prefixed with __normal_. Without being purposefully wrapped, these symbols will cause linker errors instead of silently introducing very subtle, confusing bugs. Another approach would be to whitelist symbols from libgcc and strip out all the others. The problem with this approach is that it requires the white listed symbols to be specified three times, once for objcopy, once so the linker inserts the wrapped, and once to generate the wrapper itself, while this implementation needs it to be listed only twice. There isn't much tangible difference in what each approach produces, so this one was preferred. Signed-off-by: Gabe Black <gabeblack@chromium.org>

efi: Add support for loading U-Boot through an EFI stub It is useful to be able to load U-Boot onto a board even if is it already running EFI. This can allow access to the U-Boot command interface, flexible booting options and easier development. The easiest way to do this is to build U-Boot as a binary blob and have an EFI stub copy it into RAM. Add support for this feature, targeting 32-bit initially. Also add a way to detect when U-Boot has been loaded via a stub. This goes in common.h since it needs to be widely available so that we avoid redoing initialisation that should be skipped.

efi_loader: Allow to compile helloworld.efi w/o bundling it Today we can compile a self-contained hello world efi test binary that allows us to quickly verify whether the EFI loader framwork works. We can use that binary outside of the self-contained test case though, by providing it to a to-be-tested system via tftp. This patch separates compilation of the helloworld.efi file from including it in the u-boot binary for "bootefi hello". It also modifies the efi_loader test case to enable travis to pick up the compiled file. Because we're now no longer bloating the resulting u-boot binary, we can enable compilation always, giving us good travis test coverage.
