MIPS: Loongson: Lemote-2F: Get the machine type from PMON_VER
Lemote have used the PMON_VER strings to indicate the loongson-2f machine series: PMON_VER=LM8089 Lemote 8.9'' netbook LM8101 Lemote 10.1'' netbook (The above two netbooks have the same kernel support) LM6XXX Lemote FuLoong(2F) box series LM9XXX Lemote LynLoong PC series Before the machtype is supported by the PMON, we can get the machine type from the PMON_VER for these machines, this will help the users a lot.
