MIPS: Fix generic-board-config.sh for builds using O=
When configuring the kernel using one of the generic MIPS defconfig targets, the generic-board-config.sh script is used to check requirements listed in board config fragments against a reference config in order to determine which board config fragments to merge into the final config. When specifying O= to configure in a directory other than the kernel source directory, this generic-board-config.sh script is invoked in the directory that we are configuring in (ie. the directory that O equals), and the path to the reference config is relative to the current directory. The script then changes the current directory to the source tree, which unfortunately breaks later access to the reference file since its path is relative to a directory that is no longer the current working directory. This results in configuration failing with errors such as: $ make ARCH=mips O=tmp 32r2_defconfig make[1]: Entering directory '/home/pburton/src/linux/tmp' Using ../arch/mips/configs/generic_defconfig as base Merging ../arch/mips/configs/generic/32r2.config Merging ../arch/mips/configs/generic/eb.config grep: ./.config.32r2_defconfig: No such file or directory grep: ./.config.32r2_defconfig: No such file or directory The base file '.config' does not exist. Exit. make[1]: *** [arch/mips/Makefile:505: 32r2_defconfig] Error 1 make[1]: Leaving directory '/home/pburton/src/linux-ingenic/tmp' make: *** [Makefile:145: sub-make] Error 2 Fix this by avoiding changing the working directory in generic-board-config.sh, instead using full paths to files under $(srctree)/ where necessary.
