Detail: an "instruction-fetch" response from mmioplatform to core should be an "InstFetch". This was true for successful fabric reads, but on error responses it was wrongly returned as a "DataAccess" response. This was causing a deadlock.

package SoC_Map;

|
// ================================================================
|
|
// This module defines the overall 'address map' of the SoC, showing
|
|
// the addresses serviced by each slave IP, and which addresses are
|
|
// memory vs. I/O.
|
|
|
|
// ***** WARNING! WARNING! WARNING! *****
|
|
|
|
// During system integration, this address map should be identical to
|
|
// the system interconnect settings (e.g., routing of requests between
|
|
// masters and slaves). This map is also needed by software so that
|
|
// it knows how to address various IPs.
|
|
|
|
// This module contains no state; it just has constants, and so can be
|
|
// freely instantiated at multiple places in the SoC module hierarchy
|
|
// at no hardware cost. It allows this map to be defined in one
|
|
// place and shared across the SoC.
|
|
|
|
// ================================================================
|
|
// This version of SoC_Map is for the DARPA SSITH GFE
|
|
|
|
// Our "Near_Mem_IO" corresponds to "CLINT" in Rocket
