Adds support for it in the hope that software error injection would work. With my tests with Xeon 35xx, there's still something missing. With a program that does sequencial bit writes at dev 0.0, sometimes, it produces error injection, after unblocking the MC_CFG_CONTROL (and, sometimes, it just locks my testing machine). I'll try later to discover by trial and error what's the register that solves this issue on Xeon 35xx. Signed-off-by: Mauro Carvalho Chehab --- Reading git-diff-tree failed
