Subject: [PATCH] configure.ac: Use _zicsr_zifencei extentions on riscv
From version 2.38, binutils defaults to ISA spec version 20191213. This
means that the csr read/write (csrr*/csrw*) instructions and fence.i
instruction has separated from the `I` extension, become two standalone
extensions: Zicsr and Zifencei.
The fix is to specify those extensions explicitely in -march. Since we
are now using binutils 2.38+ in OE this is ok, a more upstreamable fix for
grub will be to detect these extentions, however thats not easy to
implement
Upstream-Status: Inappropriate [OE specific]
