Istvan Csomortani 758c617c77 common/up_* : Make up_rstn synchronous to up_clk
The up_rstn is driven by s_axi_resetn, which is generated by a
Processor System Reset module. (connected to port peripheral_aresetn)
Therefor using this reset signal as an asynchronous reset is redundant,
and a bad design practice at the same time. Asynchronous reset should be
used if it's inevitable.

Lars-Peter Clausen de4fe30238 library: Match s_axi_{awaddr,araddr} signal width to peripheral memory map size
The external s_axi_{awaddr,araddr} signals that are connect to the core
have their width set according to the specified size of the register map.

If the s_axi_{awaddr,araddr} signal of the core is wider (as it currently
is for many cores) the MSBs of those signals are left unconnected, which
generates a warning.

To avoid this make sure that the signal width matches the declared register
map size.

Istvan Csomortani 9055774795 all: Update license for all hdl source files
All the hdl (verilog and vhdl) source files were updated. If a file did not
have any license, it was added into it. Files, which were generated by
a tool (like Matlab) or were took over from other source (like opencores.org),
were unchanged.

New license looks as follows:

Lars-Peter Clausen 9550c7f352 up_axi: Allow to configure AXI address width
Not all peripherals need the full address space. To be able to infer the
size of the address space of a peripheral allow the size of the AXI address
signals to be configurable rather than hardcoding its width to 32 bit.

Matthew Fornero b99117e686 up_axi: Same cycle BVALID/READY fails on Altera
The Qsys interconnect does not handle the assertion of BVALID on the
same cycle as [A]WREADY. Add a single cycle of delay to prevent
deadlocks.

Lars-Peter Clausen 6ad589475a up_axi: Prevent read and write requests from racing against each other
Make sure that if a read and a write request arrive on the very same clock
cycle to only accept one of them. The simple solution chosen here is to only
accept the write request when this happens and delay the acceptance of the
read request until the write request is finished.

This solution is not fair since a write request will always take precedence,
which in theory allows the write bus to starve the read bus. But in practice
we should never see that many write requests that we are unable to answer
the read request.
