Such boards are * supported assuming the following: * * - GPIO pins are configured by the firmware, * - CDM configuration (clocking) is setup correctly by firmware, * - if the 'fsl,has-wdt' property is present in one of the * gpt nodes, then it is safe to use such gpt to reset the board, * - PCI is supported if enabled in the kernel configuration * and if there is a PCI bus node defined in the device tree. * * Boards that are compatible with this generic platform support * are listed in a 'board' table. */ #undef DEBUG #include <asm/time.h> #include <asm/prom.h> #include <asm/machdep.h> #include <asm/mpc52xx.h> /* * Setup the architecture */ static void __init mpc5200_simple_setup_arch(void) { if (ppc_md.progress) ppc_md.progress("mpc5200_simple_setup_arch()", 0); /* Map important registers from the internal memory map */ mpc52xx_map_common_devices(); /* Some mpc5200 & mpc5200b related configuration */ mpc5200_setup_xlb_arbiter(); mpc52xx_setup_pci(); } /* list of the supported boards */ static const char *board[] __initdata = { "anonymous,a3m071", "anonymous,a4m072", "anon,charon", "ifm,o2d", "intercontrol,digsy-mtc", "manroland,mucmc52", "manroland,uc101", "phytec,pcm030", "phytec,pcm032", "promess,motionpro", "schindler,cm5200", "tqc,tqm5200", NULL }; /* * Called very early, MMU is off, device-tree isn't unflattened */ static int __init mpc5200_simple_probe(void) { return of_flat_dt_match(of_get_flat_dt_root(), board); } define_machine(mpc5200_simple_platform) { .name = "mpc5200-simple-platform", .probe = mpc5200_simple_probe, .setup_arch = mpc5200_simple_setup_arch, .init = mpc52xx_declare_of_platform_devices, .init_IRQ = mpc52xx_init_irq, .get_irq = mpc52xx_get_irq, .restart = mpc52xx_restart, .calibrate_decr = generic_calibrate_decr, };
