Florent Kermarrec 675b455259 build: always use platform.add_source and avoid manipulate platform.sources directly 2019-10-17 12:17:36 +02:00
Florent Kermarrec 43f5d1ef13 build/generic_platform: replace set with list for sources/verilog_include_paths
Python does not have native OrderedSet and we need to be able to preserve the order of the sources
for some backends (Verilator for instance), so use list instead of set.

cpu/rocket: swap main_mem and io regions
2019-10-09 21:25:57 +02:00
Gabriel Somlo f8f643a02f cpu/rocket: swap main_mem and io regions
The total size of RAM (main_mem) can be expected to vary significantly,
and often exceed the size needed for MMIO allocations by a large margin.

As such, place Rocket's MMIO (io regions) below 0x8000_0000, and start
the RAM (main_mem) at 0x8000_0000, with nothing above it to limit its
future growth.

Also, bump the pre-built Rocket verilog submodule to an updated version,
which also comes with matching changes to the way MMIO and RAM accesses
are mapped and routed to their respective AXI interfaces.

Florent Kermarrec a4ef9b29b9 soc_core/cpu: add io_regions and deprecate shadow_base (with API retro-compat)
The shadow_base parameter has always been difficult to apprehend, replace it with
io_regions (uncached regions) defined user or the CPU.

The equivalent of a shadow_base parameter of 0x80000000 in the old API is:
io_regions = {0x80000000: 0x80000000} # origin, length

It's still possible to use shadow_base with retro-compat, but user is encouraged
to update and features will be removed in the future.

builder: use the SoC's existing shadow base with get_csr_header()
2019-10-08 21:15:54 +02:00
Gabriel Somlo 53777391e8 builder: use the SoC's existing shadow base with get_csr_header()
Both the SoC and get_csr_header() have independently set defaults
for the value of 'shadow_base'. If the SoC's value was modified,
ensure that get_csr_header() uses the modified value instead of
its own default.

RFC: optional '-nowidelut' flag for yosys synth_ecp5
2019-10-06 14:55:44 +02:00
Gabriel L. Somlo 6aa76b1df8 trellis, versa_ecp5: optional '-nowidelut' flag for yosys synth_ecp5
Passing '-nowidelut' to yosys' synth_ecp5 command improves area utilization
to the point where a (linux variant) rocket-chip based design will fit on a
versa_ecp5 board. Usually '-nowidelut' incurs a timing penalty, but that is
then mitigated by using DSP inference (enabled by default from yosys commit
8474c5b3).

Off by default, this flag can be enabled by adding '--yosys-nowidelut=True'
to the litex/boards/targets/versa_ecp5.py command line.
