[Buildroot] [PATCH 00/28] Use the best FPU strategies on 32-bits Arm Cortex

[Giulio Benetti]

Hi All,

this patchset aims to enable the best FPU strategy for every board with
32-bits Arm Cortex actually present in Buildroot. I don't own these boards
so I can't test these changes. What is about Allwinner doesn't worry me
because I've tested a lot of cases with Olimex boards, but the other
changes are still to be tested.

So I ask to the board maintainers to test the patches that involve their
boards if possible. Anyway I've checked well all the SoCs Datasheet and I
think I've made it correctly, even if in some of them it's not specified
if VFPv4 means -D32. I assume it like that because otherwise -D16 is
usually specified.

Best regards
