soc/SoCBusHandler: Integrate interconnect code since avoid duplication and simplify reuse.
...
Also extends supported data_widths.
A simple custom interconnect can now be created with code like this:
# Create 2 AXI Masters / 2 AXI Slaves.
axi_m_0 = axi.AXIInterface(data_width=32, address_width=32)
axi_m_1 = axi.AXIInterface(data_width=64, address_width=32)
axi_s_0 = axi.AXIInterface(data_width=512, address_width=32)
axi_s_1 = axi.AXIInterface(data_width=512, address_width=32)
axi_s_0_region = SoCRegion(origin=0x00000000, size=0x10000000)
axi_s_1_region = SoCRegion(origin=0x10000000, size=0x10000000)
# Create Bus Handler .
self.custom_bus = SoCBusHandler(
name = "SoCCustomBusHandler",
standard = "axi",
data_width = 512,
address_width = 32,
bursting = True,
interconnect = "crossbar",
interconnect_register = True,
)
# Add AXI Buses.
self.custom_bus.add_master(master=axi_m_0)
self.custom_bus.add_master(master=axi_m_1)
self.custom_bus.add_slave(slave=axi_s_0, region=axi_s_0_region)
self.custom_bus.add_slave(slave=axi_s_0, region=axi_s_1_region)
# Finalize.
self.custom_bus.finalize()
print(self.custom_bus)

integration/soc/SoC: Add collection of CSRs described in Main Module (ie Top-Level).
...
CSRs added to the Main Module were silently ignored. These are now collected and automatically
added to a "main" Sub-Module.
This feature is useful to quickly create/add CSRs in the design when debugging, ex:
# Adds a "debug" CSR to a SoC and connect register to pads:
self.debug = CSRStorage()
self.comb += pads.debug.eq(self.debug.storage).

gen/common: Introduce LiteXModule class to simplify Modules creation and avoid common mistakes.
...
LiteXModule can be used as a remplacement of Migen's Module and in this initial version:
- Automatically inherit from AutoCSR (Forgeting to inherit from AutoCSR on a Module was a common mistake).
- Simplify design creation with:
- m.module_x = .. equivalent of Migen's m.submodules.module_x = ..
- m.special_x = .. equivalent of Migen's m.specials.special_x = ..
- m.cd_x = .. equivalent of Migen's m.clock_domains.cd_x = ..
- m += module_x equivalent of Migen's m.submodules += module_x.
- m += special_x equivalent of Migen's m.specials += special_x.
- m += cd_x equivalent of Migen's m.clock_domains += cd_x.
-> Forgeting to attach a correctly a Sub-module/Special was a very common mistake and having to use
m.submodules., m.specials., m.clock_domains. was not natural.

self.csr2 = CSRStorage(n=2)
built on a SoC with 32-bit CSR data-width will have the following CSR mapping:
