Make cache 2-way associative

• Tue, 06 Apr 2010 18:27:55 +0100
• by Philip Pemberton <philpem@philpem.me.uk> [Tue, 06 Apr 2010 18:27:55 +0100] rev 7
• Make cache 2-way associative
  
  Switched from Direct Mapped to 2-Way Set Associative caches. Should boost speed
  a bit.

reduce size of caches to fit in DE1 FPGA

• Mon, 05 Apr 2010 21:00:31 +0100
• by Philip Pemberton <philpem@philpem.me.uk> [Mon, 05 Apr 2010 21:00:31 +0100] rev 6
• reduce size of caches to fit in DE1 FPGA
  
  The default cache size makes the Icache and Dcache "just a bit" too big to
  fit in the EP2C20 FPGA on the DE1 board. This commit reduces the Icache and
  Dcache sizes to the defaults shown in the LatticeMico32 Processor Reference
  Manual (pages 36 and 37).

disable caches, they use too much RAM :(
