Florent Kermarrec 13448b8260 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)

Florent Kermarrec 3603e90ed8 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).

Florent Kermarrec 1f2d4f017a integration/soc: Switch to LiteXModule and from self.submodules/self.clock_domains to self. 2022-10-27 16:04:17 +02:00
Florent Kermarrec f8702d744f gen/common/LiteXModule: Also inherit from AutoDoc. 2022-10-27 15:52:21 +02:00
Florent Kermarrec a71fd1d31b 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.

Florent Kermarrec a57f0640cc soc/interconnect/csr: Add optional support fixed CSR mapping. 
By default, location is still automatically determined but it's now possible to
specific locations:

The following module:

class MyModule(Module, AutoCSR):
    def __init__(self):
        self.csr0 = CSRStorage()
        self.csr1 = CSRStorage(n=0)
        self.csr2 = CSRStorage(n=2)

built on a SoC with 32-bit CSR data-width will have the following CSR mapping:
- 0x00 : csr1
- 0x04 : csr0
- 0x08 : reserved
- 0x0c : csr2
