Very few of changes, did you apply the changes in this one?

 [PATCH v2 6/7] [loongson] lemote-2f: add reset support

about this part in arch/mips/loongson/lemote-2f/reset.c, I have removed
the array, and used the "switch...case..." instead.

+void mach_prepare_reboot(void)
+{
+       switch (mips_machtype) {
+       case MACH_LEMOTE_FL2F:
+               fl2f_reboot();
+               break;
+       case MACH_LEMOTE_ML2F7:
+               ml2f_reboot();
+               break;
+       case MACH_LEMOTE_YL2F89:
+               yl2f89_reboot();
+               break;
+       default:
+               break;
+       }
+}
+
+void mach_prepare_shutdown(void)
+{
+       switch (mips_machtype) {
+       case MACH_LEMOTE_FL2F:
+               fl2f_shutdown();
+               break;
+       case MACH_LEMOTE_ML2F7:
+               ml2f_shutdown();
+               break;
+       case MACH_LEMOTE_YL2F89:
+               yl2f89_shutdown();
+               break;
+       default:
+               break;
+       }
+}

and also, I have replaced that f0 by PCI_MSR_CTRL in this one:

[PATCH v2 4/7] [loongson] lemote-2f: add pci support

about this part in arch/mips/pci/ops-loongson2.c:

+#ifdef CONFIG_CS5536
+               /* cs5536_pci_conf_read4/write4() will call
_rdmsr/_wrmsr() to
+                * access the regsters PCI_MSR_ADDR, PCI_MSR_DATA_LO,
+                * PCI_MSR_DATA_HI, which is bigger than PCI_MSR_CTRL,
so, it
+                * will not go this branch, but the others. so, no
calling dead
+                * loop here.
+                */
+               if ((PCI_IDSEL_CS5536 == device) && (reg <
PCI_MSR_CTRL)) {

If it's hard to find them, I will send the increment patches later.
