Machine specific options are described in the target.opt file. By convention machine specific options begin with 'm'.

For the OpenRISC 1000  we define two options, -mor32-newlib and -mor32-newlib-uart for the plain and UART enabled versions of the BSP respectively.

For each option we provide its name on one line, any parameters on subsequent lines and a final line of description. In this case the only parameter is to say that the parameter can only appear in its positive form (i.e. --mno-or32-newlib is not permitted).

mor32-newlib
Target RejectNegative
Link with the OR32 newlib library

mor32-newlib-uart
Target RejectNegative
Link with the OR32 newlib UART library
	  

These parameters can then be used elsewhere.
