Matt Johnston 5a3cdc8b22 litedram: disable block_until_ready, regenerate 
Recent litedram gets stuck at memtest unless block_until_ready=False.
(discussion in https://github.com/enjoy-digital/litedram/pull/292)

This change regenerates with latest litedram and litex

Benjamin Herrenschmidt dbb137437c acorn: Add support for the Acorn CLE 215+ 
This is a NiteFury based PCIe M2 form-factor board originally
used for mining. It contains a speed grade 2 Artix 7 200T,
1GB of DDR3 and 32MB of flash.

The serial port is routed to pin 2 (RX) and 3 (TX) of the P2
connector (pin 1 is GND).

Note: Only 16MB of flash is currently usable until code is added
to configure the flash controller to use 4-bytes address commands
on that part.
