Subject: hw/mips/loongson3_virt: Prefer using fw_cfg_init_mem_nodma()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c47d27f59278a6b7849fcdb5cb346fe31aa55b04;p=thirdparty%2Fqemu.git

hw/mips/loongson3_virt: Prefer using fw_cfg_init_mem_nodma()

fw_cfg_init_mem_wide() is prefered to initialize fw_cfg
with DMA support. Without DMA, use fw_cfg_init_mem_nodma().
