v850 port: Initial addition with BSP for simulator in GDB
Port + v850 does not have appear to have any optimized bit scan instructions + v850 does have single instructions for wap u16 and u32 + Code path optimization preferences set + Add BSP variants for each GCC CPU model flag and a README - v850e1 variant does not work (fails during BSP initialization) BSP for GDB v850 Simulator + linkcmds matches defaults in GDB simulator with RTEMS mods + crt1.c added from v850 newlib port for __main() + BSP exits cleanly + printk and console I/O work + uses clock tick from IDLE task + Tests not requiring real clock ISR work Documentation + CPU Supplment chapter for v850 added
