Anton Blanchard aa1d2b16d7 litedram: Regenerate 
Regenerate from upstream litex. Something in the update has improved
memory read and write performance quite a lot on my Nexys Video:

Before:

  Write speed: 83.2MiB/s
   Read speed: 140.4MiB/s

After:

  Write speed: 352.1MiB/s
   Read speed: 218.5MiB/s

Matt Johnston 8901e84d8d litedram: Add orangecrab-85-0.2 target 
Parameters are based on
https://github.com/gregdavill/OrangeCrab-test-sw/blob/main/hw/OrangeCrab-bitstream.py
and litex-boards orangecrab.py

rtt_nom and cmd_delay are overridden for OrangeCrab, we do the same here.

Generated with litedram and litex
62abf9c ("litedram_gen: Add block_until_ready port parameter to control blocking behaviour.")
add2746a ("tools/litex_cli: Rename wb to bus.")
