Florent Kermarrec 3afd617455 frontend/fifo: Simplify level on _LiteDRAMFIFOCtrl, fix ctrl.write on _LiteDRAMFIFOWriter. 2021-09-24 19:34:55 +02:00
Florent Kermarrec 9e9c83ce40 litedram_gen: Add Auto-Flush to UART in FIFO mode. 
In FIFO mode, backpressure is propagated to the UART and would stall the CPU
when the UART is not accepting data. Enable Auto-Flush on the UART to allow
DRAM initialization when the UART is not ready.

Florent Kermarrec e52ece0b8a litedram_gen: Block accesses on User ports until the controller is successfully initialized. 
This is convenient on some systems to decouple DRAM accesses from the init status reported by
the cores. User ports can still try to write/read data to the ports, the controlled will
just block the transfers and release them when it will be initialized.

Florent Kermarrec e0e204a514 litedram_gen: Add FIFO Mode to UART (and rename serial IOs to uart). 
It's more interesting in some design to access the UART through a FIFO like
interface than through RS232.

support (with ULX3S example)") broke building with the --sim option.
