ChangeLog:
* Support for Ethernet (using Opencores ethmac)
Following popular demand and in order to speed up current Linux developments, 
Milkymist now supports Ethernet, currently using the MAC from Opencores.
Contrary to most IPs available from Opencores, this one does get its job done, 
but, like most of the remaining IPs, it suffers from resource greediness and 
timing problems. I have been therefore unable to synthesize a complete ML401 
system-on-chip with all the previous features and Ethernet, and therefore 
Ethernet comes disabled by default in binary kits and source release.
To re-enable it, edit boards/xilinx-ml401/rtl/setup.v and uncomment the 
"`define ENABLE_ETHERNET" line. You will then need to pick other cores to 
disable.
Using this Opencores IP is merely an expedient to add Ethernet support and 
speed up software development, and it will be kicked out as soon as a better 
core is available.
* PS/2 write support (Takeshi)
Now keyboard + mouse are supported on the ML401.
* Hard reset support
This feature replaces the previous "warm boot", which did not bring the system 
to complete reset and caused problems.
Warm boot could still have been useful for debugging, but a better option is 
to use a GDB stub similar to what can be found 
gnu/src/newlib/libgloss/lm32/crt0jtag.S in the Lattice sources.
* Dropped support for the Avnet Spartan-3A board, now available as a fork.
Thanks Fallen for taking care of this. The forked project is available at:
http://github.com/fallen/milkymist-avnet
This fork will evolve in a different direction, with smaller performance and 
feature goals. Add-ons for the Spartan-3A kit such as a SDRAM module will 
probably be developed, yielding a dirt cheap FPGA development platform that 
could be still used for quite advanced softcore CPU development.
* flterm 1.1 (now has default load addresses)
* Upgraded to LatticeMico32 3.5
* Reduced drive strength for SystemACE
* New splash screen
