The current minimum GCC version is 4.9 except ARCH=arm64 requiring
GCC 5.1.

When we discussed last time, we agreed to raise the minimum GCC version
to 5.1 globally. [1]

I'd like to propose GCC 5.2 to clean up arch/powerpc/Kconfig as well.

One point I missed when I saw your patch first time, but I realised during the discussion:

Up to 4.9, GCC was numbered with 3 digits, we had 4.8.0, 4.8.1, ... 4.8.5, 4.9.0, 4.9.1, .... 4.9.4

Then starting at 5, GCC switched to a 2 digits scheme, with 5.0, 5.1, 5.2, ... 5.5

So, that is not GCC 5.1 or 5.2 that you should target, but only GCC 5.
Then it is up to the user to use the latest available version of GCC 5, which is 5.5 at the time
begin, just like the user would have selected 4.9.4 when 4.9 was the minimum GCC version.

One line below in Documentation/process/changes.rst,
I see

     Clang/LLVM (optional)  10.0.1           clang --version



Clang 10.0.1 is a bug fix release of Clang 10


I do not think GCC 5.2 is strange when we
want to exclude the initial release of GCC 5.
