As commit 7ae4a78daa ("ARM: 8969/1: decompressor: simplify libfdt
builds") stated, copying source files during the build time may not
end up with as clean code as expected.
Do similar for mips to clean up the Makefile and .gitignore.

# When you move, remove or rename generated files, you probably also update
|
|
# .gitignore and cleaning rules in the Makefile. This is the right thing
|
|
# to do. However, people usually do 'git pull', 'git bisect', etc. without
|
|
# running 'make clean'. Then, the stale generated files are left over, often
|
|
# causing build issues.
|
|
#
|
|
# Also, 'git status' shows such stale build artifacts as untracked files.
|
|
# What is worse, some people send a wrong patch to get them back to .gitignore
|
|
# without checking the commit history.
|
|
#
|
|
# So, when you (re)move generated files, please move the cleaning rules from
|
|
# the Makefile to this script. This is run before Kbuild starts building
|
|
# anything, so people will not be annoyed by such garbage files.
|
|
#
|
|
# This script is not intended to grow endlessly. Rather, it is a temporary scrap
|
|
# yard. Stale files stay in this file for a while (for some release cycles?),
|
|
# then will be really dead and removed from the code base entirely.
|
|
|
|
# These were previously generated source files. When you are building the kernel
|
|
# with O=, make sure to remove the stale files in the output tree. Otherwise,
|
|
# the build system wrongly compiles the stale ones.
