Hi, Willy, Hi Thomas v4 here is mainly with a new nolibc-test-config target from your suggestions and with the reordering of some patches to make nolibc-test-config be fast forward. run-user tests for all of the powerpc variants: $ for arch in ppc ppc64 ppc64le; do make run-user XARCH=$arch | grep status; done 165 test(s): 157 passed, 8 skipped, 0 failed => status: warning 165 test(s): 157 passed, 8 skipped, 0 failed => status: warning 165 test(s): 157 passed, 8 skipped, 0 failed => status: warning and defconfig + run for ppc: $ make nolibc-test-config XARCH=ppc $ make run XARCH=ppc 165 test(s): 159 passed, 6 skipped, 0 failed => status: warning * tools/nolibc: add support for powerpc tools/nolibc: add support for powerpc64 No change. * selftests/nolibc: fix up O= option support selftests/nolibc: add macros to reduce duplicated changes From tinyconfig-part1 patchset, required by our nolibc-test-config target Let nolibc-test-config be able to use objtree and the kernel related macros directly. * selftests/nolibc: add XARCH and ARCH mapping support Moved before nolibc-test-config, for the NOLIBC_TEST_CONFIG macro used by nolibc-test-config target Willy talked about this twice, let nolibc-test-config be able to use nolibc-test-$(XARCH).config listed in NOLIBC_TEST_CONFIG directly. * selftests/nolibc: add nolibc-test-config target selftests/nolibc: add help for nolibc-test-config target A new generic nolibc-test-config target is added, allows to enable additional options for a top-level config target. defconfig is reserved as an alias of nolibc-test-config. As suggested by Thomas and Willy. * selftests/nolibc: add test support for ppc selftests/nolibc: add test support for ppc64le selftests/nolibc: add test support for ppc64 Renamed from $(XARCH).config to nolibc-test-$(XARCH).config As suggested by Willy. * selftests/nolibc: allow customize CROSS_COMPILE by architecture selftests/nolibc: customize CROSS_COMPILE for 32/64-bit powerpc Moved here as suggested by Willy.
