When using a Ruby memory system, the Ruby configuration scripts expect to get a list of DMA ports to create the necessary DMA sequencers. Add support in the utility functions that wire up devices to append DMA ports to a list instead of connecting them to the IO bus. These functions are currently only used by the VExpress_GEM5_V1 platform.

class VExpress_GEM5_V1(RealView):

"""
|
|
The VExpress gem5 memory map is loosely based on a modified
|
|
Versatile Express RS1 memory map.
|
|
|
|
The gem5 platform has been designed to implement a subset of the
|
|
original Versatile Express RS1 memory map. Off-chip peripherals should,
|
|
when possible, adhere to the Versatile Express memory map. Non-PCI
|
|
off-chip devices that are gem5-specific should live in the CS5 memory
|
|
space to avoid conflicts with existing devices that we might want to
|
|
model in the future. Such devices should normally have interrupts in
|
|
the gem5-specific SPI range.
|
|
|
|
On-chip peripherals are loosely modeled after the ARM CoreTile Express
|
|
A15x2 A7x3 memory and interrupt map. In particular, the GIC and
|
|
Generic Timer have the same interrupt lines and base addresses. Other
|
|
on-chip devices are gem5 specific.
|
|
|
|
Unlike the original Versatile Express RS2 extended platform, gem5 implements a
|
|
large contigious DRAM space, without aliases or holes, starting at the
|
|
2GiB boundary. This means that PCI memory is limited to 1GiB.
