e35e7b2ee3 Fix routing in non-contiguous MMIO regions 
This is a temporary fix, which can generate more hardware than necessary, but this is OK for now, since this code will soon be replaced with tilelink2 code.

a7f47f3c23 Reduce default BTB size 
The old value 62 seems to have been a typo introduced over 2 years ago
in commit 63bd0b9d2a.  The intent was to
fit the dhrystone working set (rofl) which the new value of 40 does.

b76612f357 relax contraint on adding AddrMapEntry to AddrMap (#248)
