From 9a47b9660bec4ee38d27b06a3904af86f4fbd95d Mon Sep 17 00:00:00 2001 From: Stafford Horne Date: Wed, 20 Oct 2021 06:50:21 +0900 Subject: or1k: math soft float support OpenRISC support hard float but I will like to submit that after glibc soft float goes upstream. The hard float support depends on adding user access to the FPCSR, which is not supported by the kernel yet.
