[edit] long/double fields and arrays with GC redirection

use hardware for long versions of get/putfield and array access to use the GC copy redirection. When write access to fields goes only via putfield/static we can simplify the redirection.

Also change (after OEBB stabilizes) the access in the GC write barrier to Native.putfield().

[edit] IO device mapping

To reduce resource usage (data MUX in scio_*.vhd) make a mapping from IO addresses to select numbers.

• Keep one free slot to map the USB device to a dummy read_cnt="00" device
• Can we reduce the number of scio_*.vhd devices with some generate and generic?

[edit] Documentation

• Generate an actual getting started from the handbook for the web sites

[edit] Reset

• fetch.vhd jfetch is read from the ROM, but the value is not defined on reset - is an issue in the Actel
