2016-01-19scripts/Makefile* Add SPDX-License-Identifier tagTom Rini
A general best practice for SPDX is that Makefiles should have an identifier, add these as everything else is currently covered. Signed-off-by: Tom Rini <trini@konsulko.com>
2014-11-04kbuild: do not hide clang warnings during build with W=1Masahiro Yamada
These lines originate in Linux; it looks like Linux folks chose to hide bunch of warnings reported by clang rather than fixing C code. In U-boot, warnings are being fixed thanks to Jeroen's great efforts. Let's stop suppressing clang warnings.

2014-08-21kbuild: move extra gcc checks to scripts/Makefile.extrawarnMasahiro Yamada
This commit was imported from Linux Kernel: commit a86fe353 written by me. W=... provides extra gcc checks. Having such code in scripts/Makefile.build results in the same flags being added to KBUILD_CFLAGS multiple times becuase scripts/Makefile.build is invoked every time Kbuild descends into the subdirectories. Since the top Makefile is already too cluttered, this commit moves all of extra gcc check stuff to a new file scripts/Makefile.extrawarn, which is included from the top Makefile.
