Thanks! This is my first time ever sending a patch to Buildroot and
admittedly I'm not very well versed with all details in Buildroot, so
pardon my ignorance here and I appreciate the guidance I get.

Chapter 17.3 and 17.4 is about this in the documentation, right?

For hash files, are you referring to these:

$ find -name "*.hash" | grep gcc
./package/gcc/gcc-initial/gcc-initial.hash
./package/gcc/gcc.hash
./package/gcc/gcc-final/gcc-final.hash

I.e. add a line to each of them stating the source and the hash of the
tarball itself? Only use SHA-512 I suppose? The documentation lists both
SHA1 and SHA-256.

Btw, what is the difference between the three (initial, ..., final)?


Regarding the makefiles, same there?

$ find -name "*.mk" | grep gcc
./package/gcc/gcc.mk
./package/gcc/gcc-initial/gcc-initial.mk
./package/gcc/gcc-final/gcc-final.mk

After looking at those it's not directly clear what I'm supposed to
update there.
