NOTICE

UberDDR4 source notices
======================

The original UberDDR4 controller, PHY, top and prober files carry Angelo
Jacobo's GNU GPL version 3-or-later notices. COPYING supplies the unmodified
GNU GPL version 3 text referenced by those headers. Existing file-level
copyright and license notices remain authoritative.

The following imported ZipCPU/Dan Gisselquist modules retain their own Apache
License 2.0 notices and upstream references:
  rtl/axi/axi_addr.v
  rtl/axi/axim2wbsp.v
  rtl/axi/aximrd2wbsp.v
  rtl/axi/aximwr2wbsp.v
  rtl/axi/skidbuffer.v
  rtl/axi/wbarbiter.v
  formal/fwb_slave.v

rtl/axi/sfifo.v carries Gisselquist Technology's public-domain dedication
and warranty disclaimer, retained in its header.

See those headers for attribution and the license reference. This inventory
does not assign a new license to files without an explicit license notice.

AMD/Xilinx primitive libraries, generated IP, and the Micron behavioral model
are external dependencies with their own supplied terms. The model setup
script links or copies files from the user's installed Vivado distribution;
the vendor model is not included in this source release. The Linux project
manages additional external software and toolchain dependencies separately.
