At the moment the link [1] does not work. It is redirected to nonexisting "http://wiki.prplfoundation.org//MIPS_documentation"; (prplfoundation.org site problem?).
The http://wiki.prplfoundation.org/wiki/MIPS_documentation URL works.
The "MIPS documentation" wiki page contains many documents so can we use
more accurate URL, e.g. http://wiki.prplfoundation.org/wiki/MIPS_documentation#Unified_Hosting_Interface ?
Can we use more strict name for "MIPS UHI specification", e.g. "Unified Hosting Interface Reference Manual (MD01069)"?
