5c19b133ac soc/interconnect/packet: add > 8-bit support to Packetizer/Depacketizer
With high speed link (10gbps XGMII ethernet for example), stream data_width is generally
> 8-bit which make header/data un-aligned on bytes boundaries. The change allows the
Packetizer/Depacketizer to work on stream with a data_width > 8-bit.

28708f4208 cpu/rocket: parameterize axi interface data width
Rocket variants can be configured with axi port data widths that
are multiples of the native word size (64 bits in our case). In
the future, we will add variants with mem_axi data width > 64 bit,
to match the native data width of the LiteDRAM controller on
various development boards (e.g., 128 bits on the ecp5versa, and
256 bits on the trellisboard).

ec831f5b63 cpu/rocket, soc_sdram: Connect mem_axi to LiteDRAM, bypass WB bus
Connect Rocket's dedicated port for cached RAM accesses (mem_axi)
directly to the LiteDRAM data port, bypassing the shared LiteX
(Wishbone) bus.

When both Rocket's mem_axi and LiteDRAM's port have the same data
width, use a native point-to-point AXI connection.

Otherwise, convert both ends to Wishbone, and use the Wishbone
data width converter to bridge the gap.
FIXME: In the future, this part should be replaced with a native
AXI data width converter!

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.

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.

ensure that get_csr_header() uses the modified value instead of

ffd2be2ba0 csr: add we signal to CSR, CSRStatus
Doing actions on register read is generally not a good design practice (it's
better to do separate register write to trigger actions) but in some very
specific cases being able to know that register has been read can solve cases
that are difficult to do with the recommended practives and that can justify
doing an exception.


This commit add a we signal to CSR, CSRStatus and this allow the logic to know
when the CSR, CSRStatus is read.

131971986c integration: add ModuleDoc and AutoDoc
It is important to be able to document modules other than CSRs.
This patch adds ModuleDoc and AutoDoc, both of which can be used
together to document modules.

ModuleDoc can be used to transform the __doc__ string of a class into a
reference-manual section.  Alternately, it can be used to add additional
sections to a module.

AutoDoc is used to gather all submodule ModuleDoc objects in order to
traverse the tree of documentation.

5844376d53 soc_core: adapt memory map for mainline Linux with mor1kx
Mainline Linux expects it to be loaded at the physical address of 0x0.
Change the MAIN_RAM base address to 0x0 and update exception vector
during the booting process.

f909e4d706 integration/builder: When the CPU is "None", we used to not generate any code.
With this change, we will now generate csr.h and sdram_phy.h, which
will be needed by the initialization code running on the host CPU.

60d8572c3e csr_eventmanager: add name and description args
Add `name` and `description` as optional arguments to the various
EventSource types.  These default to `None`, so this should be a
backwards-compatible change.

Use the same trick as CSRs, where we default the `name` to be the
instantiated object name as read from the Migen `get_obj_var_name()`
call.
