reduce size of caches to fit in DE1 FPGA

• 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 :(

remove more Lattice-specific fluff

• remove more Lattice-specific fluff
  
  Code now synthesizes properly on Altera Quartus 9.0 build 235

Disable Lattice-specific stuff by default

• Disable Lattice-specific stuff by default
  
  To build on Lattice platforms, `define PLATFORM_LATTICE in lm32_include.v.
  Otherwise, non-optimal "platform independent" HDL will be used.
  This means LM32 can now be built for non-Lattice FPGAs.

remove need for system_conf.v
