Subject: mem-ruby: Remove function that maps responses to a DMA engine
X-Git-Tag: v19.0.0.0~2383
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9737d93eb1d22946073d448c0c9200169f1a0b64;p=gem5.git

mem-ruby: Remove function that maps responses to a DMA engine

The function map_Address_to_DMA was used to route responses to the
first (and assumed to be the only) DMA engine in the system. This
function is now unused as protocols handle responses and route them to
the right DMA engine.
