From: Hervé Poussineau Date: Sat, 14 Sep 2013 15:51:09 +0000 (+0200) Subject: lsi: add 53C810 variant X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ceae18bd74e8940ff79935a257c72e665b084bcc;p=qemu.git lsi: add 53C810 variant Currently, treat it exactly as a 53C895A. 53C895A is a 53C810 with more capabilities, so this should work. However, this lets us test different code paths on Linux, which don't use lastest features if it detect a 810, or on some OSes which only support 810 and not 895A (like very old Windows NT versions).
