Florent Kermarrec 0607e926c8 com/liteethmini/phy: remove use of FlipFlop in MII 2015-10-23 20:23:45 +02:00
Rohit Kumar Singh 71993edae4 Add init file in sdram/phy dir
Without __init__.py file, when using setup.py, setuptools' find_package() function does not find the files in sdram/phy package. Hence .egg file entirely misses sdram/phy directory

More info here: https://bitbucket.org/pypa/setuptools/issues/97

Florent Kermarrec b2a4eead0c uart/software: remove litescope dependency 2015-09-21 09:04:59 +02:00
Florent Kermarrec 31956de790 dvisampler/edid: fix sda sampling, needs to be similar to scl.
Video sources with high scl frequency were not able to access EDID information through I2C.
I2C start was not detected correctly and was randomly reseting the fsm during transfers.(seen with litescope)

Florent Kermarrec 40f47f447a create liteethmini and move liteeth to a separate repo (https://github.com/enjoy-digital/liteeth)
LiteEthMini is a subset of LiteEth intended to be used with a CPU and a software stack.

Florent Kermarrec a1e4183b3f sdram/phy/s6ddrphy: fix comment on S6QuarterRateDDRPHY 2015-08-22 12:50:41 +02:00
Florent Kermarrec de87d65f68 sdram/module: add P3R1GE4JGF DDR2 (Atlys) and MT41J128M16 DDR3 (Opsis, Novena) modules. 2015-08-22 12:42:44 +02:00
Florent Kermarrec 50e857e99c sdram/phy/s6ddrphy: add S6QuarterRateDDRPHY to run DDR3 at higher frequencies.
Built on top of S6HalfRateDDRPHY, exposes a 4 phases DFI interface to the controller with a 2x slower clock.
Validated on the Numato Lab opsis board (50MHz sys_clk/ DDR400), should also work on the Novena laptop (same DDR3 module).

Florent Kermarrec 8bb30a8620 liteeth/phy: fix autodetect (clk_freq not necessary passed in kwargs) 2015-08-22 12:08:49 +02:00
Florent Kermarrec 158fbe49ac sdram/phy/s6ddrphy: rename S6DDRPHY to S6HalfRateDDRPHY and use ORed wrdata_en/rddata_en (the controller already manages that) 2015-08-22 11:47:26 +02:00
Florent Kermarrec 4acab79987 sdram/module: cleanup indent 2015-08-20 22:15:06 +02:00
Florent Kermarrec 63538a7d04 litecores: add -Ob option to make.py (allow to build with yosys for example) 2015-08-19 01:17:37 +02:00
Florent Kermarrec 3d3cd128d8 liteeth/phy: only use clk_freq for LiteEthPHYGMIIMII in autodetect 2015-08-19 01:17:35 +02:00
Florent Kermarrec 3cf46671e9 liteeth/phy: rename rgmii to s6rgmii since specific to Spartan6
Also remove autodetection support for RGMII. For it to work we would need to pass the device we are building for.

Florent Kermarrec 4b8d9b67f3 liteeth: add rgmii phy 2015-08-05 00:50:55 +02:00
Florent Kermarrec c03ef526eb sdram/phy/s6ddrphy: add DDR3 support 2015-08-04 12:29:42 +02:00
Florent Kermarrec 52fba05e26 sdram/phy/initsequence: add burst chop 4 (BC4) for DDR3
This is needed for half rate controllers with burst length of 4.
For best efficiency quarter rate controllers should be used.

whitequark 4b6bd43d8e Enable ror, ffl1 and addc for OR1K. 2015-07-30 10:55:01 +03:00
whitequark a4e14f1058 Don't build base libraries and BIOS with -fPIC after all. 2015-07-29 12:09:05 +03:00
Sebastien Bourdeauducq b7aff65ca9 mor1kx: enable ADDC, CMOV and FFL1 instructions 2015-07-29 00:08:21 +08:00
Sebastien Bourdeauducq f2eff4d10e soc: increase default BIOS size 2015-07-28 22:36:42 +08:00
whitequark c8ffd0c9ee Switch to -fPIC.
Using -fPIC for everything allows to link the MiSoC static libraries
both into static images such as the BIOS as well as
into shared libraries.

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.
