openrisc: fix trap for debugger breakpoint signalling
I have been working on getting native Linux GDB support working for the OpenRISC port. The trap signal handler here was wrong in a few ways. During trap handling address (from the EEAR register) is not set by the CPU, so it is not correct to use here. We want to use trap as a break-point so use TRAP_BRKPT. Adding 4 to the pc was incorrect and causing GDB to think the breakpoint was not hit. Fixing these allows GDB to work now. Signed-off-by: Stafford Horne <shorne@gmail.com>
