From 2bfd3654a61e3e0214754a2742a4bf69aedc643e Mon Sep 17 00:00:00 2001 From: John Paul Adrian Glaubitz Date: Wed, 4 Mar 2020 14:31:34 +0100 Subject: [PATCH] build: Add soft-float handling for SuperH (sh4) While GRUB has no platform support for SuperH (sh4) yet, this change adds the target-specific handling of soft-floats such that the GRUB utilities can be built on this target.
