Florent Kermarrec 70c1491d1c ddr3_mr_gen: Display RZQ/x with --list (Useful for comparison with MIG's settings expressed in RZQ/x). 2022-02-24 14:44:02 +01:00
Florent Kermarrec e48471ea43 phy/s7ddrphy: Expose write_latency_calibration parameter and revert it to True by default. 2022-02-23 10:36:42 +01:00
Florent Kermarrec a0580c7ae7 frontend/axi: Add Write Buffer reservation mechanisms to know when we have enough data in the buffer to generate the command. 2022-02-17 17:21:02 +01:00
Florent Kermarrec 963233aefb litedram_gen: Add ECC support on ports and add example on kcu105. 2022-02-16 11:34:36 +01:00
Florent Kermarrec 68c082bf20 frontend/axi: Only switch between read/write at the end of a burst. 2022-02-15 18:05:47 +01:00
Florent Kermarrec 497bbc0394 frontend/axi: Improve similarities in aw/ar handling. 2022-02-15 17:43:38 +01:00
Florent Kermarrec 72ca120fa0 frontend/axi/LiteDRAMAXI2NativeW: Decouple axi.w from axi.aw and allow buffering in w_buffer without waiting for cmd to be accepted. 2022-02-15 17:34:09 +01:00
Florent Kermarrec 5f722a1513 bench/test: Avoid use of ident_version (should fix CI). 2022-02-15 17:33:31 +01:00
Florent Kermarrec e6758539d9 litedram_gen: Minor cosmetic cleanup. 2022-02-08 18:28:57 +01:00
Florent Kermarrec 24fad45764 frontend/dma/LiteDRAMDMAReader: Make sure to flush FIFO/Reservation counter when disabled. 2022-01-17 10:56:09 +01:00
Florent Kermarrec 62abf9ce0c litedram_gen: Add block_until_ready port parameter to control blocking behaviour. 
In some cases, blocking the port until controller is ready is not wanted (ex on No-CPU
config where a port is used for the memtest).
 2022-01-13 21:51:57 +01:00
Florent Kermarrec 2d47363f46 test/benchmark: Switch from soc_sdram (deprecated) to soc_core. 2022-01-07 18:37:13 +01:00
Florent Kermarrec e5e3b6c9a3 phy/s7ddrphy: Only do write latency calibration on Kintex7/Virtex7. 
This has been causing issues on Artix7 and is only required with write_leveling.

Matt Johnston 7560435d07 phy/ecp5ddrphy: Bring back dm_remapping 
This allows swapping UDM/LDM pins. Was removed in
af9abd6ec9
 phy/ecp5ddrphy: remove dm_remapping introduce for VexRiscv-SMP on OrangeCrab...

But is still useful for native port uses of litedram

Add dm_swap parameter to gen.py
