From 5861b585e70167a61ed324a94274204e7c3ad5b3 Mon Sep 17 00:00:00 2001 From: Martin Roth Date: Wed, 17 Aug 2016 21:51:28 -0600 Subject: [PATCH] qemu-riscv: Remove obsolete CSR - send_ipi MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This aligns the code in qemu-riscv with the code in spike-riscv. The previous code gives an error in the updated toolchain as the send_ipi CSR is no longer valid. This gave the build error: src/mainboard/emulation/qemu-riscv/qemu_util.c:64: Error: Instruction csrw requires absolute expression Change-Id: Iac0f66e8e9935f45c8094d5e16bedb7ac5225424 Signed-off-by: Martin Roth Reviewed-on: https://review.coreboot.org/16244 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel Reviewed-by: Ronald G.
