dde49d52e4 - the w11a rbus interface used so far a narrow dynamically adjusted
rbus->ibus window. Replaces with a 4k word window for whole IO page.
- utilize rlink protocol version 4 features in w11a backend
  - use attn notifies to dispatch attn handlers
  - use larger blocks (7*512 rather 1*512 bytes) for rdma transfers
  - use labo and merge csr updates with last block transfer
  - this combined reduces the number of round trips by a factor 2 to 3, 
    and in some cases the throughput accordingly.

d87ac86f53 - migrate to rlink protocol version 4
- Goals for rlink v4
    - 16 bit addresses (instead of 8 bit)
    - more robust encoding, support for error recovery at transport level
    - add features to reduce round trips
      - improved attention handling
      - new 'list abort' command
  - For further details see README_Rlink_V4.txt
- use own C++ based tcl shell tclshcpp instead of tclsh

093d540121 - The div instruction gave wrong results in some corner cases when either
divisor or quotient were the largest negative integer (100000 or -32768).
  This is corrected now, for details see ECO-026-div.txt
- some minor updates and fixes to support scripts
- xtwi usage and XTWI_PATH setup explained in INSTALL.txt

4732555297 - interim release w11a_V0.581 (untagged)
- new reference system
  - switched from ISE 13.3 to 14.7.
  - map/par behaviour changed, unfortunately unfavorably for w11a. 
    On Nexys3 no timing closure anymore for 80 MHz, only 72 MHz can 
    be achieved now.
- new man pages (in doc/man/man1/)
- support for Spartan-6 CMTs in PLL and DCM mode
