2018-06-24efi: stub: Move the use_uart assignment immediately after ↵Bin Meng
exit_boot_services() call The use_uart assignment should follow immediately after the call to exit_boot_services(), in case we want some debug output after that. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2018-06-24efi.h: Do not use config optionsAlexander Graf
Currently efi.h determines a few bits of its environment according to config options. This falls apart with the efi stub support which may result in efi.h getting pulled into the stub as well as real U-Boot code. In that case, one may be 32bit while the other one is 64bit. This patch changes the conditionals to use compiler provided defines instead. That way we always adhere to the build environment we're in and the definitions adjust automatically.

2018-06-17x86: use EFI calling convention for efi_main on x86_64Ivan Gorinov
UEFI specifies the calling convention used in Microsoft compilers; first arguments of a function are passed in (%rcx, %rdx, %r8, %r9). All other compilers use System V ABI by default, passing first integer arguments of a function in (%rdi, %rsi, %rdx, %rcx, %r8, %r9). These ABI also specify different sets of registers that must be preserved across function calls (callee-saved). GCC allows using the Microsoft calling convention by adding the ms_abi attribute to a function declaration. Current EFI implementation in U-Boot specifies EFIAPI for efi_main() in the test apps but uses default calling convention in lib/efi. Save efi_main() arguments in the startup code on x86_64; use EFI calling convention for _relocate() on x86_64; consistently use EFI calling convention for efi_main() everywhere.
