Florent Kermarrec 8d1c555e36 misoclib/com/uart: remove irq condition parameters and use "non-full" for tx irq, "non-empty" for rx irq.
An optimal solution for both sync and async mode is not easy to implement, it would requires moving CDC out of UART module and handling in the PHY with AsyncFIFO or minimal depth.
For now use the solution that works for both cases. We'll try to optimize that if we have performance issues.

Florent Kermarrec ce11b30140 misoclib: integrate mxcrg.py in mlabs_video target, remove others directory
we should also get rid of mxcrg.v (similar to what is done on papilio or pipstrello)

Florent Kermarrec b75b93df43 misoclib/com/uart: replace revered Migen FIFO function with specific _get_uart_fifo function for our use case. 2015-07-24 14:05:54 +02:00
Florent Kermarrec 0a115f609e litepcie/frontend/dma: group loop index and count in loop_status register (avoid 2 register reads) 2015-07-24 13:52:57 +02:00
Florent Kermarrec d73d75007e misoclib/com/uart: cleanup and add irq condition parameters
- reintroduce RX/TX split (ease comprehension)
- use FIFO wrapper function from Migen.
- add tx_irq_condition and rx_irq_condition

Florent Kermarrec dfc207aacb litepcie: use data instead of dat in dma_layout (allow use of migen.actorlib.packet modules on dma dataflow) 2015-07-22 21:44:53 +02:00
Florent Kermarrec 40740d3ddc litepcie: use optional platform.misoc_path to add litepcie phy wrapper verilog files
We should eventually try to use python package_data or data_file for that.

Robert Jordens 097248bce9 uart.c: rx overflow fix and tx simplification
* fixes the clearing of the rx ringbuffer on rx-overflow
* removes tx_level and tx_cts by restricting the ringbuffer
  to at least one slot empty
* agnostic of the details of the tx irq: works for uarts that
  generate tx interrupts on !tx-full or on tx-empty.
* only rx_produce and tx_consume need to be volatile

Florent Kermarrec 35250f5b11 bios: add romboot
When firmware is small enough, it can be interesting to run code from an embedded blockram memory (faster and not impacted by memory controller activity).
It can also be a fallback option in case boot from flash failed.
To use this, define ROM_BOOT_ADDRESS and initialize the blockram with the firmware data.
