The SOC in a raspi is probably no worse than the rest, but consider that the 
natural entropy available (for Crypto) to a SOC is much lower than a 
multi-component system like a laptop or tower. The Raspi 1.xx has an onboard 
entropy chip you can enable, if you trust it, and there'll be a new device in 
/dev you can read raw entropy from. Write that to /dev/random to seed the 
system pool and use /dev/urandom as your actual source.

Personally I'd draw from several sources to feed /dev/random: an internal 
hash-chain (quick Python script) (re)seeded on a password and urandom 
periodically, the hardware entropy generator, Ubuntu's seed server.. don't 
trust one source, mash them up once a minute/hour and feed them to /dev/random.
