Aded papilio duo

Added low memory type 2 - for papilio and its 512k

Resync output to input hsync

Added multiple build types

Added 32 bit sram access to make zpu work

fixed ucf use

sram works, boots, keyboard works

Fixed PLL to more appropriate for PAL/NTSC with he 32MHz input clock. Should work now, although no ZPU yet!

replacing with pal/ntsc plls of correct input frequency

First cut of papilio duo support. NB: This does not work yet, notably PLL needs changing. Then sram needs wiring up to allow zpu to run.

Added inferred multiplier

EDBLL apparently works with lower drive strength - there are some crosstalk issues I read. Added GPIO lower drive strength. Removed 25ohm resistors.

Now builds ok - disabled some features to fit in device. Also optimised pokey mixer.

Space reduction to fit onto a Spartan 6 LX9. Allow disabling stereo and covox. Also replace pokey non-linear table with a piecewise linear function rather than a LUT

New GPIO layout for PBI implementation

Fix write through problem

Fix some timing issues on faster CPUs - e.g. ARM on SOCKIT

Add shadow hardware regs hack as in zpu

Fixed delay function on sockit

Accidentally broken...

Important note!

Few scripts to program FPGA

Added rbf

SOCkit first working version - with sound, drive emulation, typing. Lots of debugging to do - e.g. system does not yet unfreeze. Lots of implement - no SDRAM yet, no USB controllers yet etc. Still I am pleased with how well it goes given how complex this board is!

Fix for write with verify
