hw/riscv: pfsoc: add missing FICs as unimplemented
Browse files Browse the repository at this point in the history 
The Fabric Interconnect Controllers provide interfaces between the FPGA
fabric and the core complex. There are 5 FICs on PolarFire SoC, numbered
0 through 4. FIC2 is an AXI4 slave interface from the FPGA fabric and
does not show up on the MSS memory map. FIC4 is dedicated to the User
Crypto Processor and does not show up on the MSS memory map either.

FIC 0, 1 & 3 do show up in the MSS memory map and neither FICs 0 or 1
are represented in QEMU, leading to load access violations while booting
Linux for Icicle if PCIe is enabled as the root port is connected via
either FIC 0 or 1.
