Florent Kermarrec af94e8497a litedram_gen: Enable Read-Modify-Write support with ECC. 2022-02-28 18:52:32 +01:00
Florent Kermarrec 095180be6a frontend/AXI: Add optional Read-Modify-Write mode for cases where w.strb is not available on the DRAM side (ex when ECC is enabled). 
When enabled, partial writes are automatically detected and a Read-Modify-Write access is
done. Before doing a RMW access, pending accesses are terminated and incoming accesses are
stalled until RMW access is done.

Enable with_read_modify_write in test_axi.

Florent Kermarrec 81ae73b74a test/test_axi: Exercise w.strb through randomness (as we are doing for data). 2022-02-28 18:35:39 +01:00

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 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).

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.

This allows swapping UDM/LDM pins. Was removed in

 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
