Indeed - that was me! Fun times. I'm all up & running on CentOS 7.2 now,
though, thanks to the help of you fine folks on here.

One thing I did change was to not boot via TFTP since I'd rather not have
booting dependent on network availability. Instead I'm loading via SD. It
was pretty straight forward but, in case anyone else is interested, I 
replaced the load_tianocore variable like so (assuming dev 0, part 1):

setenv load_tianocore 'fatload mmc 0:1 0x82000000 mp30ar0_tianocore_ubt.fd;
fatload mmc 0:1 0x1d000000 mp30ar0_tianocore_sec_ubt.fd'

Stoked. Thanks again, guys!
