	Stefan thinks they don't add value. Command used: sed -i -e '/file is part of /d' $(git grep "file is part of " \|egrep ":( /\.\/\$\|#\|;#\|-- \| \ )" \| cut -d: -f1 \|grep -v crossgcc \|grep -v gcov \| grep -v /elf.h \|grep -v nvramtool) The exceptions are for: - crossgcc (patch file) - gcov (imported from gcc) - elf.h (imported from GNU's libc) - nvramtool (more complicated header) The removed lines are: - fmt.Fprintln(f, "/* This file is part of the coreboot project. /") -# This file is part of a set of unofficial pre-commit hooks available -/ This file is part of coreboot / -# This file is part of msrtool. -/ This file is part of msrtool. / - This file is part of ncurses, designed to be appended after curses.h.in -/* This file is part of pgtblgen. / - This file is part of the coreboot project. - /* This file is part of the coreboot project. / -# This file is part of the coreboot project. -# This file is part of the coreboot project. -## This file is part of the coreboot project. --- This file is part of the coreboot project. -/ This file is part of the coreboot project / -/ This file is part of the coreboot project. / -;## This file is part of the coreboot project. -# This file is part of the coreboot project.

2015-06-05	lib: Unify log2() and related functions	Julius Werner
	This patch adds a few bit counting functions that are commonly needed for certain register calculations. We previously had a log2() implementation already, but it was awkwardly split between some C code that's only available in ramstage and an optimized x86-specific implementation in pre-RAM that prevented other archs from pulling it into earlier stages. Using __builtin_clz() as the baseline allows GCC to inline optimized assembly for most archs (including CLZ on ARM/ARM64 and BSR on x86), and to perform constant-folding if possible. What was previously named log2f on pre-RAM x86 is now ffs, since that's the standard name for that operation and I honestly don't have the slightest idea how it could've ever ended up being called log2f (which in POSIX is 'binary(2) LOGarithm with Float result, whereas the Find First Set operation has no direct correlation to logarithms that I know of). Make ffs result 0-based instead of the POSIX standard's 1-based since that is consistent with clz, log2 and the former log2f, and generally closer to what you want for most applications (a value that can directly be used as a shift to reach the found bit). Call it __ffs() instead of ffs() to avoid problems when importing code, since that's what Linux uses for the 0-based operation. CQ-DEPEND=CL:273023 BRANCH=None BUG=None TEST=Built on Big, Falco, Jerry, Oak and Urara. Compared old and new log2() and __ffs() results on Falco for a bunch of test values.
