| Subject: arm64: Adjust EFI libstub object include logic |
| |
| From: Steve Capper <steve.capper@linaro.org> |
| |
| commit ad08fd494bf00c03ae372e0bbd9cefa37bf608d6 upstream. |
| |
| Commit f4f75ad5 ("efi: efistub: Convert into static library") |
| introduced a static library for EFI stub, libstub. |
| |
| The EFI libstub directory is referenced by the kernel build system via |
| a obj subdirectory rule in: |
| drivers/firmware/efi/Makefile |
| |
| Unfortunately, arm64 also references the EFI libstub via: |
| libs-$(CONFIG_EFI_STUB) += drivers/firmware/efi/libstub/ |
| |
| If we're unlucky, the kernel build system can enter libstub via two |
| simultaneous threads resulting in build failures such as: |
| |
| fixdep: error opening depfile: drivers/firmware/efi/libstub/.efi-stub-helper.o.d: No such file or directory |
| scripts/Makefile.build:257: recipe for target 'drivers/firmware/efi/libstub/efi-stub-helper.o' failed |
| make[1]: *** [drivers/firmware/efi/libstub/efi-stub-helper.o] Error 2 |
| Makefile:939: recipe for target 'drivers/firmware/efi/libstub' failed |
| make: *** [drivers/firmware/efi/libstub] Error 2 |
| make: *** Waiting for unfinished jobs.... |
| |
| This patch adjusts the arm64 Makefile to reference the compiled library |
| explicitly (as is currently done in x86), rather than the directory. |
