2020-06-11de0: fix UART RTS/CTS direction.Ivan Grokhotkov
RTS and CTS match the schematic, but the direction is incorrect: CTS is output, RTS is input. Fix by setting role=dce. Ref. https://www.intel.com/content/dam/altera-www/global/en_US/portal/dsn/42/doc-us-dsnbk-42-5804152209-de0-user-manual.pdf
2020-06-11[breaking-change] nexys4ddr: fix UART RTS/CTS pins.Ivan Grokhotkov
According to the schematic, RTS is E5 and CTS is D3. Previously these were reversed to work around signal direction set in UARTResource. Un-reverse the signals, and set correct direction by passing role=dce. Ref. https://reference.digilentinc.com/_media/nexys4-ddr:nexys_4_ddr_sch.pdf
2020-06-11[breaking-change] blackice: remove UART RTS/CTS signals.Ivan Grokhotkov
According to the schematic, RTS and CTS are not connected to CH340G in this version of the board. Ref. https://github.com/monsonite/BackIce_FPGA/blob/master/BlackIce18_07_01D.pdf and https://forum.mystorm.uk/uploads/default/original/1X/a5db1ce1c9bc2d91e63cfdc8424d699c2419a3d0.png
2020-06-11blackice_ii: fix UART RTS/CTS direction.Ivan Grokhotkov
Pin numbers match the P0/P1 signals in the schematic, but the direction is reversed. Fix by setting role="dce". Ref. https://github.com/mystorm-org/BlackIce-II/blob/master/hardware/BlackIce.pdf
2020-06-11[breaking-change] resources: distinguish "dte"/"dce" roles of UART.Ivan Grokhotkov
UARTResource gets a new argument, "role", which determines flow control signal directions: - DCE means that the design acts as a modem - DTE means that the design acts as a PC

2019-10-03[breaking-change] Fix polarity of "dm" signal in "memory" resource.whitequark
LB# and UB# enable writing their corresponding byte. The "m" in "dm" means mask; that is, logical high masks (prevents) the byte from being written. This means that it should use Pins(), not PinsN(), to get the behavior implied by "mask".
