Subject: [Qemu-devel] [PATCH] hw/pci-host/q35: Replace hardcoded value with macro
Date: Wed, 25 Apr 2018 17:20:37 +0800 [thread overview]
Message-ID: <1524648037-5010-1-git-send-email-whois.zihan.yang@gmail.com> (raw)
Currently part of mch_realize uses hardcoded value when initializing
smram regions. Use macro to be more clear to code readers
