I don't think the reset button differs between boards.  As far as I know, the 
issues are really just that it doesn't reset everything -- specifically some of 
the IP on the chip (clock, power, JTAG) isn't reset and nothing on the board 
(SD, ethernet, PCIe, etc) is reset.  This frequently results in flakiness when 
debugging drivers, but the cores and memory system should all be OK.

Is that issue 65 on github.com/opensbi?  If so it clearly says this isn't a 
reset button issue.
