powerpc/ppc4xx: Make gdsys 405ep boards reset more generic
In order to add boards that have different hardware for fpga reset, any 405ep gdsys board now provides these functions: void gd405ep_init(void); void gd405ep_set_fpga_reset(unsigned state); void gd405ep_setup_hw(void); int gd405ep_get_fpga_done(unsigned fpga); Signed-off-by: Dirk Eibach <eibach@gdsys.de> Cc: Stefan Roese <sr@denx.de> Signed-off-by: Stefan Roese <sr@denx.de>
