From 65638f8d6b1f438ae442bad7a4f77b188d3d3689 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Mon, 26 Dec 2022 11:36:03 +0800 Subject: [PATCH] lib: utils/sys: Allow custom HTIF base address for RV32 commit 6dde43584f18 ("lib: utils/sys: Extend HTIF library to allow custom base address") forgot to update do_tohost_fromhost() codes for RV32, which still accesses the HTIF registers using the ELF symbol address directly.
