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 d73d75007e misoclib/com/uart: cleanup and add irq condition parameters

Tested successfully with BIOS and flterm.

Florent Kermarrec 096e95cb59 uart: use data instead of d on endpoint's layouts (coherency with others cores) 2015-03-01 16:56:48 +01:00
