0ea7a1fd05 soc_core/sdram: Don't blow up if _wb_sdram_ifs or _csr_masters are empty
For example a standalone controller with no exposed CSRs (probably not
a very useful configuration but I really don't like python backtraces)

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.

201218b2c3 boards/targets: increase integrated ROM size if EthernetSoC is used
Currently section '.rodata' of the LiteX BIOS doesn't fit in the 'rom'
region if mor1kx is used with EthernetSoC. Increase the integrated ROM
size from 0x8000 to 0x10000 in EthernetSoC.

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.
