hmmm hmmm not sure - let's see how everyone's getting on, who can do
what.  waiting to hear from Dimitry (who is waiting for NLnet to pay the
donation for work already done, and the paperwork needs "Libre-SOC Team"
to be added to MoUs for that to happen)

so do carry on for now, but keep an eye out on this page to "plan ahead" if
you know what i mean
https://libre-soc.org/openpower/sv/bitmanip/

some of those are read simple, some are not, so a decision needs to be
made as to which ones go in, and why.  bear in mind, some assembler
routines are needed to "demo" them as "actually being useful" for
speeding up / reducing power on cryptographic routines (that's the
point of the NLnet crypto-primitives Grant)
