Hi,
after building the just released GCC 7.3.0 compiler I get the below failure when building U-Boot. This is when building the EFI helloworld example, which seems to be enabled by default. Manually disabling CONFIG_CMD_BOOTEFI_HELLO_COMPILE fixes the U-Boot build (but of course doesn't fix that particular problem). I see this with origin/master, v2018.01 and v2017.11, but only with GCC 6.4.0 and 7.3.0, but not with 7.1.0. So I guess it's the compiler that got more picky.
The splat is: ============= aarch64-linux-ld.bfd: arch/arm/lib/crt0_aarch64_efi.o: relocation R_AARCH64_ABS16 against `EFI_SUBSYSTEM' can not be used when making a shared object scripts/Makefile.lib:399: recipe for target 'lib/efi_loader/helloworld_efi.so' failed =============
It's beyond me at the moment what causes this or how to fix it, but I hope you guys can find a solution?
Cheers, Andre.
