/**
* Geode systems write protect the BIOS via RCONFs (cache settings similar

* writing to MSRs, however requires instructions rdmsr/wrmsr, which are
* ring0 privileged instructions so only the kernel can do the read/write.
* This function, therefore, requires that the msr kernel module be loaded
* to access these instructions from user space using device /dev/cpu/0/msr.
*
* This hard-coded location could have potential problems on SMP machines
* since it assumes cpu0, but it is safe on the Geode which is not SMP.
*
* Geode systems also write protect the NOR flash chip itself via MSR_NORF_CTL.
* To enable write to NOR Boot flash for the benefit of systems that have such
* a setup, raise MSR 0x51400018 WE_CS3 (write enable Boot Flash Chip Select).
*
* This is probably not portable beyond Linux.
