17 Ethernet testbench speed penalty solved. Now Ethernet of testbench and minsoc can be enabled by only uncommenting `define ETHERNET on minsoc_defines.v.

send_mac, get_mac and uart_send tasks have been included/improved. Also a testbench, which works for both included firmwares is added. (eth and uart)

If ETHERNET is defined for the SoC, both firmwares will complete successfully. If not, the eth firmware will stall when trying to access the Ethernet module.

16 Further initialization improvement of non-used signals, setting interrupt signals to 0 if module is not used. rfajardo 4194d 14h /minsoc/trunk/rtl/verilog/minsoc_top.v
14 Wishbone error signal of Ethernet core was not tied to ground if Ethernet was disabled. Solved now. rfajardo 4203d 15h /minsoc/trunk/rtl/verilog/minsoc_top.v
7 Some changes:
-wb_cabs removed from minsoc_top.v and minsoc_tc_top.v
-added reset polarity control to minsoc_defines.v through:
-minsoc_onchip_ram_top.v does not use
minsoc_onchip_ram.v oe signals (output enable) anymore,
which are implemented as tristate buffers. Now
minsoc_onchip_ram_top.v has a generated MUX, which
has an arbitrary number of inputs and 1 output.
Input are the internal output of the onchip_rams,
output the wb_dat_o.
