* zpu_core_small: loadAlvaro2010-10-221-0/+1
| | | | | | | memAAddr is not being initialized during IO read operations (LOAD). This might cause spurious writes to invalid addresses, and invalid values to be loaded onto the stack. This patch explicitly sets memAAddr to correct value (sp).

* I'm also attaching another patch which removes unisim/roc dependencyoharboe2008-06-181-0/+1
| | | | | | | | | | (it was used just to pulse the areset) and fixes paths for building the ghdl examples out of the box. I guess this is the easiest way to get zpu running on linux with minimum effort. You should check if the areset change doesn't break modelsim. It feels much simpler this way and seems to work the same, i might be missing something.
